© 2020 Elsevier Ltd The increasing contamination of lead ions (Pb(II)) in groundwater has become a serious environmental issue, which provides the impetus for intense research on Pb(II) removal. e-MnO2 nanoflowers were successfully fabricated through a simple decomposition reaction. And the obtained e-MnO2 nanoflowers were employed to remove Pb(II) from water. The detailed microstructure and surface properties of e-MnO2 were systematically characterized. The results indicate that the pure e-MnO2 phase was obtained and the specific surface area is 96.33 m2 g-1. Batch adsorption experiments of Pb(II) were carried out, and the e-MnO2 nanoflowers exhibited outstanding adsorption performance. The maximum adsorption capacity for Pb(II) and Cd(II) achieved to 239.7 mg g-1 and 73.6 mg g-1 at the dosage of 0.2 g L-1. Besides, the prepared e-MnO2 nanoflowers show much higher removal efficiency toward Pb(II) compared with commercial MnO2. The XRD results reveal the stability of e-MnO2 nanoflowers, and the XPS results suggest that both the electrostatic interaction and structural tunnels are responsible for the removal mechanisms of Pb(II). This work finds a facile method to synthesize e-MnO2 nanoflowers, showing great potential for Pb(II) removal.

© 2020 Elsevier B.V. A magnetic field activated drug delivery and pH-sensitive controlled drug release system based on carboxyl-modified green synthesized Fe3O4@SiO2 (Fe3O4@SiO2-Glu) nanoparticles was established. Doxorubicin hydrochloride (DOX), as a drug model, was adsorbed onto the Fe3O4@SiO2-Glu nanoparticles' surface, where the observed drug loading capacity of 34.6 mg/g was attributed to electrostatic interaction between -COO¿ on the surface of Fe3O4@SiO2-Glu and -NH3+ of DOX. The structure, morphology and physiochemical properties of Fe3O4@SiO2-Glu were characterized via TEM, FTIR, XRD, N2 adsorption/desorption isotherms, and Zeta potential measurements. The green synthesized Fe3O4@SiO2-Glu nanoparticles exhibited multilayer architecture with a BET surface area of 79.9 m2/g and a magnetization saturation of 25.9 emu/g. Drug release experiments indicated that DOX was pH trigger released with 60.8% released within 72 h at pH 3.5. This system has important potential implications for the design of more effective and stable magnetic Fe3O4@SiO2-Glu materials as drug carriers for targeted and controlled drug release.

© 2020 Elsevier Ltd Ubiquitous use of antibiotics worldwide has resulted in their significant efflux into the environment impacting ecosystem health to such a degree that antibiotic removal has become a key environmental issue. Here one target antibiotic, rifampicin, was successfully removed from aqueous solution using a hybrid nanomaterial (rGO@Fe/Pd NP) having an adsorption capacity of 90.9 mg g-1. The factors influencing rifampicin removal by rGO@Fe/Pd NPs and each constituent component of the hybrid nanomaterial were also investigated. Adsorption and reduction kinetics indicated that rifampicin conformed to a pseudo-second-order model. While X-ray diffraction and Fourier transform infrared spectroscopy showed that rifampicin was adsorbed by rGO@Fe/Pd NPs, scanning electron microscopy and X-ray photoelectron spectroscopy showed that rifampicin was reduced by nano iron and during this process, nano palladium acted as a catalyst. Liquid chromatography-mass spectrometry, confirming that rifampicin was indeed catalytically degraded by rGO@Fe/Pd NPs, as evidenced by a decrease in ion mass ratio from 823.41 (M+1H) to 611.21 (M+1H) or 606.37 (M+1H). A mechanism for rifampicin degradation based on adsorption and catalytic reduction was proposed. In addition, the practical removal efficiency of rifampicin was successfully validated in aquaculture sewage water (71.9%) and for municipal sewage (58.1%). This article provides a strong scientific basis for the degradation mechanism of rifampicin by rGO@Fe/Pd NPs indicating that this hybrid material has great potential for practical applications.

© 2019, Science Press. All right reserved. Green synthesized nanomaterials have been successfully used to remove heavy metals in wastewater, immobilizing heavy metals in soils is still unclear.In this study, iron oxide nanoparticles (GION) were prepared from euphorbia cochinchinensis extract and following used to immobilize cadmium (Cd) in soil, where soil was tested under after 60 and 120 d incubation with a 50% water hold capacity with control.Results show ¿the Cd in soil were immobilized effectively by GION, and there was no significantly difference between 60 and 120 d, indicating that the immobilization of Cd by GION was stability in 60 d and 120 d incubation.At 120 d, the available Cd (0.1 mol¿L-1 CaCl2) in the 1%, 3% and 9% GION treatments decreased by 19.1%, 16.7%, 66.7%, and he exchangeable Cd (Tessier) decreased by 12.5%, 18.8%, 56.3% respectively.¿the pH and Fe species in soil increased with increasing GION dosage, resulting in decreasing the available of Cd effectively.With increasing in pH.The (NH4)C2O4-Fe and DCB-Fe increased by 0.4, 2.9, 6.0 times and 0.7, 1.1 and 1.9 times, respectively.In addition, in the GION treatments, (NH4)C2O4-Fe and DCB-Fe increased, while HCl-Fe2+ decreased with incubation time, indicating that GION affected the activity of iron species in soil, and enhancing its biochemical process and transform it into a more stable fractions, leading to further change the fraction of Cd in soil by SEM-EDS. Furthermore, the abundance of Fe in the 9% GION treatment was much higher than that of the control.¿the activity of urease and invertase activity increased, while catalase did not change significantly, revealing that GION immobilized Cd by reducing the bioavailability of cadmium in soil, resulting in the increasing enzyme activity.Since GION is environmentally friendly and in the stable immobilizing Cd.GION could be potentially used to Cd in contaminated soil.

© 2018, Science Press. All right reserved. Bentonite supported Fe/Ni nanoparticles (Bent-Fe/Ni) was prepared by chemical reduction in aqueous solution, and was used to remove amoxicillin. The effects of different concentrations of anions (SO42- and HCO3-) and cations (Ca2+ and Cu2+) on the reduction of amoxicillin using Bent-Fe/Ni were investigated. The results indicated that SO42- and HCO3-was a major factor on the reduction of amoxicillin, where the removal efficiency of amoxicillin reduced from 93.7% to 21.5%, and 93.7% to 5.8% when the concentration of SO42- and HCO3- increased from 0 to 500 mg¿L-1. However, the removal efficiency of amoxicillin reduced from 93.7% to 77.8% as the concentration of Ca2+ increased from 0 to 500 mg¿L-1, suggesting that the coexisted Ca2+ inhibited the reduction of amoxicillin. In addition, 93.7%, 94.8% and 86.7% of amoxicillin was removed as the concentration of Cu2+ was 0, 10 and 100 mg¿L-1, respectively, indicating that low concentration of Cu2+ promoted the reduction of amoxicillin and the high concentration of Cu2+ inhibited the reduction of amoxicillin.

© 2018, Editorial Board, Research of Environmental Sciences. All right reserved. In order to study the influences of organic acids on degradation of amoxicillin using bentonite supported Fe/Ni (B-Fe/Ni), the effect of humic acid (HA) and ethylenediamine tetraacetic acid (EDTA) on degradation of amoxicillin was investigated. The effects of different mass concentrations of HA (0, 10, 50 and 100 mg/L) and EDTA (0, 10, 50 and 100 mg/L) on the degradation of amoxicillin by B-Fe/Ni were systematically analyzed. The materials were characterized by scanning electron microscope (SEM) and X-ray diffraction (XRD). The results revealed that the degradation rates of amoxicillin in the systems containing 0, 10, 50, and 100 mg/L of mass concentration of HA were 63.6%, 88.6%, 87.3% and 81.8%, respectively under 10 minutes reaction time, while the degradation rates of amoxicillin in the systems containing 0, 10, 50, and 100 mg/L of mass concentration of EDTA were 63.6%, 74.3%, 65.7%, and 33.6%, respectively. The result of analysis of SEM and XRD showed that iron oxide or hydroxide precipitates and passivation layer formed as the reaction progress. HA and EDTA can promote the degradation of amoxicillin by B-Fe/Ni at low mass concentration of HA and EDTA, while inhibit the degradation of amoxicillin at high mass concentration.

© 2018, Chongqing Functional Materials Periodical Press Co. Ltd. All right reserved. The coated iron nanoparticles (CA-ELE-Fe NPs) were synthesized using eucalyptus leaves extract and calcium alginate (CA). The results showed that 74.7% of diesel was removed using CA-ELE-Fe and H2O2, while only 13.19% and 10.15% of diesel oil were removed by CA-ELE-Fe and H2O2 after 240 min, respectively, which demonstrated that CA-ELE-Fe NPs exhibit a good adsorption ability and act as excellent Fenton-like catalyst. Scanning electron microscopy (SEM), X-ray energy dispersive spectroscopy (EDS) and Fourier transform infrared spectroscopy (FT-IR) confirmed the successful synthesis of iron nanoparticles and indicated the changes in CA-ELE-Fe NPs before and after reaction with oil. Various materials were applied to treat practical oil wastewater, which showed that 80.24%, 82.47% and 44.36% of diesel was removed by CA-ELE-Fe NPs, green synthetic nano particles (ELE-Fe NPs) and zero-valent iron nanoparticles (nZVI), respectively. Meanwhile, diesel removal efficiency reached 67.46% by used CA-ELE-Fe NPs, because the coating of calcium alginate reduced the iron nanoparticles releasing to liquid.

© 2017, Science Press. All right reserved. The biodegradation efficiencies of dyes were inhibited in the presence of heavy metals. In this study, EDTA was used as a Cr chelating agent to increase the degradation efficiency of malachite green (MG) by Burkholderia cepacia C09G. The results show that the biodegradation efficiency of MG at 01 mmol¿L-1 was 962% at 24 h. However, the MG removal efficiency was only 67% at 60 h in the presence of 05 mmol¿L-1 of Cr (VI), while 188% was obtained if amended with 05 mmol¿L-1 of EDTA. When concentration of EDTA was 05 mmol¿L-1, the optimal chelating concentration of Cr(VI) was 07 mmol¿L-1, where the degradation efficiency of MG was 353% and adsorption efficiency of Cr(VI) was 246%. In addition,the EDS, SEM and XPS analysis confirm that the adsorbed Cr(VI) was reduced to Cr(III) by Burkholderia cepacia C09G and the toxicity of Cr(VI) alleviated due to the chelation of EDTA

© 2017 Elsevier B.V. In this paper, a green and facile synthesis of reduced graphene oxide (GO) by Eucalyptus leaf extract (EL-RGO) was investigated, which was characterized with ultraviolet-visible spectroscopy (UV), Raman spectroscopy, X-ray diffraction (XRD), scanning electron microscope (SEM), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS) and Thermal gravimetric analysis (TG). Eucalyptus leaf extract also play both reducing and capping stabilizing agents prepared EL-RGO as shown a good stability and electrochemical properties. This approach could provide an alternative method to prepare EL-RGO in large-scale production. Moreover, the good electrochemical property and biocompatibility can be used in various applications. In addition, the merit of this study is that both the oxidized products and the reducing agents are environmental friendly by green reduction.

© 2017, Science Press. All right reserved. Green-reduced graphene oxide (G-rGO) film electrode and bio-reduced graphene oxide (B-rGO) film electrode are used as anodes in microbial fuel cells (MFCs) to examine their performance in electricity generation. The anodes were characterized by fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscope (SEM). Furthermore, the electrochemical techniques such as cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) were applied to explore the electrochemical performance. The internal resistances of G-rGO group was 243.87 O with the maximum power densities and output voltage at 18.77 W·m-3 and 760 mV, respectively. However, the internal resistances of unmodified group and B-rGO group were larger at 375.21 O and 299.11 O. Besides, lower power density and output voltage were shown at 8.97 W·m-3 and 480 mV for control group and 13.16 W·m-3 and 635 mV for B-rGO group. Above all, it demonstrates that G-rGO film anodes performed better and can be applied as anode materials in MFC to accelerate electricity generation.

© 2017, Science Press. All right reserved. In this study, the cationic surfactant cetyl trimethyl ammonium bromide (CTAB) was used at different concentrations as both a stabilizing and dispersing agent to improve the function of IONP and to remove nitrite in an aqueous solution. The removal efficiency of nitrite using 0.4 mmol·L-1 CTAB was 97.32% at an initial nitrate concentration of 20 mg·L-1, which was 23% higher than that of IONP. The results from SEM and FTIR indicated that CTAB improved the dispersion and stability of IONP, thereby enhancing the latter's reactivity. A kinetic study, conducted in this work, showed that the adsorption of nitrite by IONP fit the pseudo-first order, while the adsorption of nitrite by CTAB-IONP fit the pseudo-second order.

© 2017, Science Press. All right reserved. To explore the impact of different nano zero valent iron (nZVI) on microbial fuel cells (MFC) in the start-up phase, in this study, MFCs were setting up with different anodic substrates: sludge (control group), sludge containing chemical synthetic nZVI (c-nZVI group) and sludge containing green synthetic nZVI (g-nZVI group), respectively, and MFCs tested by five cycles. In the start-up process of g-nZVI group and c-nZVI group, a high concentration of nZVI could inhibit electricity generation, while nZVI made no essentially change in voltage output after MFC starting successfully. The results obtained from COD removal rate, SEM and electrochemical characterization showed that green synthesis of nZVI, was less likely to enrich on the electrode surface, change the surface electronic properties and suppress bacteria activity in anode to compare chemical synthetic nZVI.

© 2016, Springer Science+Business Media Dordrecht. Microalgae are extensively used in the remediation of heavy metals like iron. However, factors like toxicity, bioavailability and iron speciation play a major role in its removal by microalgae. Thus, in this study, toxicity of three different iron salts (FeSO4, FeCl3 and Fe(NO3)3) was evaluated towards three soil microalgal isolates, Chlorella sp. MM3, Chlamydomonas sp. MM7 and Chlorococcum sp. MM11. Interestingly, all the three iron salts gave different EC50 concentrations; however, ferric nitrate was found to be significantly more toxic followed by ferrous sulphate and ferric chloride. The EC50 analysis revealed that Chlorella sp. was significantly resistant to iron compared to other microalgae. However, almost 900¿µg¿g-1 iron was accumulated by Chlamydomonas sp. grown with 12¿mg¿L-1 ferric nitrate as an iron source when compared to other algae and iron salts. The time-course bioaccumulation confirmed that all the three microalgae adsorb the ferric salts such as ferric nitrate and ferric chloride more rapidly than ferrous salt, whereas intracellular accumulation was found to be rapid for ferrous salts. However, the amount of iron accumulated or adsorbed by algae, irrespective of species, from ferrous sulphate medium is comparatively lower than ferric chloride and ferric nitrate medium. The Fourier transform infrared spectroscopy (FTIR) analysis shows that the oxygen atom and P = O group of polysaccharides present in the cell wall of algae played a major role in the bioaccumulation of iron ions by algae.

© 2016, Springer-Verlag Berlin Heidelberg. In this study, the influence of soil types on the effect of the commercial form of C-nZVI on tissue concentrations, cellular component, reproduction outcome in Eisenia fetida, and the soil health was investigated. C-nZVI at concentration level of 3¿g¿kg-1 soil showed no effect on the survival of E. fetida in the three soil types. However, varying effects such as concentration-dependent increase in tissue iron concentration, lipid peroxidation, and damage to DNA molecules by C-nZVI were observed. C-nZVI at an exposure concentration of 60¿mg¿kg-1 soil induced oxidative stress in E. fetida. Tissue Fe concentration appeared correlated to the DNA damage. Oxidative stress and DNA damage may explain the toxicity mechanisms of nZVI to E. fetida. [Figure not available: see fulltext.].

© 2016 Elsevier B.V. The development of highly efficient, eco-friendly and cost-effective remediation technology to remove mixed contaminants is now in progress. Here, agarose-Fe nanoparticles (NPs) hydrogel were produced via two green steps to remove mixed contaminants, specifically trichloroethylene (TCE) and hexavalent chromium (Cr(VI)). Approx. 84.9% of Cr(VI) and 93.8% of TCE were simultaneously removed over 24 h in their co-existing solution, while 94.1% of Cr(VI) and 97.2% of TCE were separately removed by agarose-Fe NPs hydrogel. Scanning Electron Microscopy (SEM) suggested that the macroporosity of agarose-Fe NPs hydrogel facilitated the mass transfer between agarose-Fe NPs hydrogels and mixed contaminants, and that Fe NPs were uniformly immobilized into the hydrogel. X-ray Photoelectron Spectroscopy (XPS) and Fourier Transform Infrared Spectroscopy (FTIR) provided evidence supporting the co-removal mechanism. XPS result indicated that: (1) chemical reduction played a role in the removal of both Cr(VI) and TCE; and (2) iron oxides and Fe(III)-Cr(III) complexes might be formed after reaction. FTIR result showed that some functional groups were involved in the removal process. Moreover, the presence of iron oxides were confirmed by FTIR. Both SEM and XPS results verified that encapsulation could describe such immobilization of Fe NPs using agarose. Finally, the kinetics study supported the removal mechanism. Such encapsulation of Fe NPs via a green strategy is simple, quick, and cost-effective, making in situ remediation of mixed contaminants more favorable.

© 2015 Elsevier Ltd. All rights reserved. Chitosan-stabilized nanoscale zero-valent iron (CS-nZVI) was prepared and used for the removal of acid fuchsine (AF) from aqueous solution with the assistance of ultrasound. More than 98.9% of AF was removed using CS-nZVI, aged CS-nZVI (exposed to air for 2 months), while only 14.6% removal efficiency was achieved after 15 min by chitosan alone with the assistance of ultrasound. Scanning electron microscopy (SEM) confirmed that chitosan polymers were arranged in a homocentric layered structure. Thus, the polymer can prevent the aggregation of nZVI and increase their anti-oxidation capacity. X-ray diffraction (XRD) also suggested that the chitosan used in synthesis may protect nZVI nanoparticles from air oxidation. Different factors impacting on the removal of AF using CS-nZVI showed that the reduction increased when dosage and temperature increased, but decreased when pH and initial concentration rose. Kinetic studies revealed that the removal of AF fitted well to the pseudo-first-order model. The apparent activation energy was 55.34 kJ/mol, indicating a chemically controlled reaction. Finally, the application of CS-nZVI in dyeing wastewater led to a removal efficiency of 99% of AF, while the reuse test confirmed that AF's removal efficiency declined from 99.6 to 39.3% after seven cycles.

In this study, iron based nanoparticles (Fe NPs) synthesized by eucalyptus leaf extracts was used to remove mixed Cr(VI) and Cu(II), where the efficiency was 58.9% and 33.0%, respectively. In contrast, only 20.2% of Cr(VI) and 11.8% of Cu(II) were removed by adsorption using eucalyptus leaf extracts. In addition, the removal mechanism for mixed Cr(VI) and Cu(II) based on both adsorption and reduction by Fe NPs was confirmed by various characterization techniques, including the formations of Fe NPs, iron oxides and capping layer. Furthermore, the kinetics suggested that firstly, their sorption followed the pseudo second-order model well; and secondly, reduction of Cr(VI) and Cu(II) followed the pseudo-first-order model well. Finally, Fe NPs not only removed Cr(VI) and Cu(II), but also Pb(II) and Zn(II) in electroplating wastewater. This provides a new insights into the removal of metal ions using green Fe NPs with a low cost and environmentally friendly remediation strategy.

© 2015 Elsevier B.V. To reduce cost and enhance reactivity, bimetallic Fe/Pd nanoparticles (NPs) were firstly synthesized using grape leaf aqueous extract to remove Orange II. Green synthesized bimetallic Fe/Pd NPs (98.0%) demonstrated a far higher ability to remove Orange II in 12h compared to Fe NPs (16.0%). Meanwhile, all precursors, e.g., grape leaf extract, Fe2+ and Pd2+, had no obvious effect on removing Orange II since less than 2.0% was removed. Kinetics study revealed that the removal rate fitted well to the pseudo-first-order reduction and pseudo-second-order adsorption model, meaning that removing Orange II via Fe/Pd NPs involved both adsorption and catalytic reduction. The remarkable stability of Fe/Pd NPs showed the potential application for removing azo dyes. Furthermore, Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR) confirmed the changes in Fe/Pd NPs before and after reaction with Orange II. High Performance Liquid Chromatography-Mass Spectrum (HPLC-MS) identified the degraded products in the removal of Orange II, and finally a removal mechanism was proposed. This one-step strategy using grape leaf aqueous extract to synthesize Fe/Pd NPs is simple, cost-effective and environmentally benign, making possible the large-scale production of Fe/Pd NPs for field remediation.

© 2015 Elsevier B.V. Microcystin-LR (MC-LR) as a drinking water contaminant was degraded using iron-based nanoparticles such as nZVI, Fe/Ni and Fe/Pd. Batch experiments showed that 28.0% of MC-LR with the initial concentration of 5mgL-1 was removed using nZVI, while more than 90% of MC-LR was removed using either bimetallic Fe/Ni or Fe/Pd after degrading for 120min. In addition, the results indicated that Fe0 was oxided to iron oxide or hydroxide after reacting with MC-LR, while Ni or Pd acted as the catalysis to prevent Fe0 corrosion and generating hydrogen via water reduction. Degradation of MC-LR by iron-based nanoparticles fitted well to the pseudo-first order kinetic model and the degradation was a diffusion-controlled reaction with low activation energies (8-21kJmol-1). Finally, the degradation mechanisms of MC-LR using iron-based nanoparticles were proposed according to the LC-MS analysis. In nZVI case, when the MC-LR was quickly adsorbed on nanoparticles, electron transfer and H2 generated from iron corrosion were generated and broke down the Adda composition of MC-LR. Based on corrosion in the Fe0-H2O system, bimetallic Fe/Ni and Fe/Pd further utilized the abundant hydrogen radical decomposed from H2 under the catalysis of Ni or Pd, and destroyed the Adda to form small molecules.

© 2016 The Royal Society of Chemistry. A new functional biomaterial based on Burkholderia vietnamiensis C09V (C09V) was immobilized on beads and used for simultaneous removal of both heavy metals and crystal violet (CV). The results showed that removal of CV and metal ions using immobilized cell bead (biomaterial) was more efficient than that of free cells, wherein 89.4% of CV and 64.1% of Cu(ii) were removed after 42 h of using the biomaterial, whilst only 27.1% of CV and 23.9% of Cu(ii) were removed by free cells. Similar results were also observed in the CV and Cr(vi) removal. Fourier transform infrared spectroscopy (FTIR) revealed the change of functional groups in the presence of heavy metals. Scanning electron microscopy (SEM) showed that the existence of Cu(ii) and Cr(vi) affected the cellular morphology of the strain. X-ray energy-dispersive spectrometer (EDS) indicated that Cu(ii) and Cr(vi) adsorbed. Further Cr(vi) reduced to Cr(iii) was observed by X-ray photoelectron spectroscopy analysis (XPS). Finally, reusability and wastewater application were carried out, which shows that this functional material has a potential for co-removal of CV and heavy metals.

© 2016 American Chemical Society. Despite many reports being published on using biodegradation or Fenton-like oxidation to remove various containments, the integration of these two processes to improve the removal efficiency of contaminants is still a challenge. This study attempted to remove naphthalene and phenanthrene from aqueous solution using a sequential biodegradation and Fenton-like oxidation based on green synthesis of iron nanoparticles (Fe NPs). Results showed that after 96 h, 100% naphthalene was biodegraded, whereas only 28.9% phenanthrene and 48.3% chemical oxygen demand (COD) were removed, respectively, indicating that the biodegradation was an incomplete process and the degraded metabolites still existed. To improve the removal efficiency of phenanthrene and the degraded metabolites, Fenton-like oxidation based on Fe NPs synthesized using tea extracts under various atmospheres (N2, O2 and air) was employed. Results indicated 100% of phenanthrene was removed, total COD removed increased to 81.5%, 77.2% and 68.7% using N2, O2 and air-Fe NPs, respectively. In addition, Fe NPs were confirmed by scanning electron microscopy (SEM) and X-ray energy-dispersive spectroscopy (EDS). Finally, the degraded metabolites were identified by GC-MS to understand the degradation pathway.

© 2016 Elsevier Ltd. This study investigated the use of cetyltrimethylammonium bromide (CTAB) as a stabilizer in green synthesis to improve the reactivity of iron oxide nanoparticles (IONP). Results show that efficiency in removing phosphate increased from 71.0% to 97.3%. To understand how to improve the reactivity of IONP by CTAB: firstly, characterizations of IONP before and after phosphate removal by SEM, EDS, FTIR, XPS show the adsorption of P onto the IONP; secondly, batch experiments indicate that the adsorption capacity of phosphate increased when temperature or initial phosphate concentration increased and decreased with an increase in both adsorbent dose and pH. Adsorption followed the pseudo-second-order kinetics model and the equilibrium data fitted well to the Langmuir isotherm. Thermodynamic data confirmed the spontaneous and endothermic nature of the adsorption process. Finally, it was proposed that the adsorption of phosphate using CTAB-modified IONP was mainly associated with inner-sphere complexing mechanism and electrostatic attraction.

© 2016 Elsevier B.V. This paper investigated modified bamboo charcoal (MBC) as a cheap, abundant and alternative cell immobilization matrix for biodegrading diesel oil. The immobilized microorganism's degradation capacity was compared to its free form counterparts, namely planktonic and immobilized bacteria which degraded relatively high amounts of diesel oil (>80%). Acinetobacter venetianus immobilized on MBC demonstrated superior efficiency in degrading diesel oil (94%) compared to planktonic cells culture (82%) over a 3-day period. Moreover, the simultaneous adsorption and biodegradation of diesel oil using these immobilized cells fitted well to the pseudo second order (R2 > 0.99). Scanning electron microscopy (SEM) revealed that through absorption, cells attached well to the cavum of MBC stalk cells. Fourier transform infrared analysis (FTIR) revealed that a large number of bands at 1300-1500 cm-1 existed, demonstrating that the diesel oil was degraded and new bands were formed. Gas Chromatography Mass Spectrum (GC-MS) analysis indicated the immobilized cells could degrade diesel oil into esters and aldehydes. Results justified the applicability of MBC as the carrier matrix for immobilizing microorganisms in removing diesel oil compounds from industrial wastewater.

© 2016 Elsevier Inc. All rights reserved. Removal of chlorine gas (Cl2) from air is of critical requirement in order to address point-source emissions possibly during a terrorist attack or an industrial accident resulting in Cl2 contamination of the atmosphere. In this work, copper (Cu) exchanged zeolite Y (CuY) was functionalised with triethylenediamine (TEDA) and the capacity to remove Cl2 was evaluated. The materials were characterised by nitrogen (N2) adsorption-desorption studies, Fourier Transform Infrared (FTIR) spectroscopy and X-ray Photoelectron Spectroscopy (XPS). The materials' ability to remove Cl2 was investigated via a dynamic breakthrough test. Copper exchanged zeolite displayed a low adsorption of Cl2 in spite of its large surface area. However, Cl2 removal greatly improved following functionalisation with TEDA. XPS analysis revealed that Cl2 was removed via a catalytic hydrolysis reaction where adsorbed water vapour transformed Cl2 into Cl- which could be further trapped in the zeolite structural framework. Moisture could increase the Cl2 removal capacity, but the competition for adsorption between water and chlorine molecules was also observed. The spent adsorbent after exposure to Cl2 could be easily recycled with an excessive water vapour treatment. The reusability was also investigated and the adsorbent could be used for more than five times. This material can potentially be used in air filters. It may provide an efficient way for decontaminating Cl2 during a terrorist attack or an industrial accident.

© 2016 Elsevier B.V. This study investigates the effect of humic acid, oxalate and phosphate on the heterogeneous Fenton-like oxidation efficiency of microcystin-LR (MC-LR) using zero-valent iron nanoparticles (nZVI) as a catalyst at neutral pH. The degradation efficiency of MC-LR in the Fenton-like system increases significantly from 59.1% to 78%, and 59.1% to 72.1% in the presence of humic acid and oxalate, respectively. These mean that humic acid and oxalate are able to form complexes with iron and iron oxide, thus promote the Fenton-like oxidation of MC-LR. However, the degradation efficiency reduces from 59.1% to 47.8% in the existence of phosphate, because phosphate adsorbs competitively with MC-LR to the nZVI surface, consequently inhibits the heterogeneous Fenton-like oxidation of MC-LR. The oxidation kinetics of MC-LR fits well with the pseudo first-order kinetic model. The results illustrate that humic acid was more effective than oxalate and phosphate to generate hydroxyl radicals. The surface changes of nZVI before and after reaction were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR).Magnetite, maghemite, lepidocrocite and other iron complexes were detected at nZVI surfaces after reaction with MC-LR.

© 2016 Elsevier B.V. This study examines the modification of bentonite with humic acid (HAB) as a novel sorbent for simultaneous removal of Cu(II) and 2,4-dichlorophenol (2,4-DCP) from aqueous solution. Batch experiments were conducted employing either single sorption or simultaneous sorption of Cu(II) and 2,4-DCP. Results indicated that the sorption of either Cu(II) or 2,4-DCP onto HAB was little influenced by the presence of the other contaminant. The amount of sorption was 22.40 mg g- 1 and 14.23 mg g- 1 for Cu(II) and 2,4-DCP, respectively at 30 °C. Scanning electron microscopy (SEM) indicated that HA was immobilized on the surface of bentonite. Energy dispersive spectroscopic (EDS) analysis indicated that Cu(II) was sorbed onto HAB. X-ray diffraction (XRD) analysis demonstrated that the crystalline structure of bentonite did not change after being modified with HA. Fourier-transform infrared (FTIR) spectra confirmed that new bonds and band intensity emerged after the sorption of Cu(II) and 2,4-DCP onto the HAB. These suggest that simultaneous sorption of 2,4-DCP and Cu(II) onto HAB could occur through: firstly, a mechanism that partitions between 2,4-DCP and HA; and secondly, the ion-exchange mechanism between Cu(II) and bentonite.

© 2015 Elsevier B.V. All rights reserved. The green synthesis of functional iron nanoparticles (Fe NPs) by tea extracts was used as a catalyst for the Fenton-like oxidation of malachite green (MG), where more than 85% of MG was removed. The new findings are that the removal of MG by Fe NPs was based on the adsorption of MG onto iron oxide and degradation of MG by iron nanoparticles. This was confirmed by adsorption and degradation kinetics, indicating that: firstly, the adsorption kinetics follows the pseudo-first-order model; and secondly, degradation kinetics fitted well to the pseudo-second-order model. Morphology, size and changes in the Fe NPs surface were characterized using SEM, XRD, and FTIR techniques, showing that Fe<inf>2</inf>O<inf>3</inf> and Fe<inf>3</inf>O<inf>4</inf> was formed and green tea extract contained a high concentration of caffeine/polyphenols. It acted as both reducing and capping agents in the synthesis of Fe NPs. To further confirm the removal mechanism of MG by the functional Fe NPs, the degraded products were identified by FTIR and GC-MS analysis. Finally the mechanism of Fenton-like oxidation of MG based on both adsorption and degradation was proposed.

© 2015, Science Press. All right reserved. Green synthesis of iron nanoparticles (Fe NPs) using plant extracts is one of the potential approaches in environmental remediation. This study is aimed to investigate the removal efficiency of Pb(II) and Cd(II) using Fe NPs synthesized by Ilex latifolia leaf extracts and the effect of temperatures. The results showed that the decrease of removal efficiency of Pb (II) from 93.8% to 91.0% was observed when Cd (II) was present, while the removal efficiency of Cd (II) significantly decreased from 41.7% to 31.4% when Pb (II) was co-presented by a dosage of 2.0 g·L-1 Fe NPs (pH=3.5, 303 K) in 60 min. The removal kinetics of Pb(II) and Cd(II) followed a pseudo-first-order and a pseudo-second-order equation, respectively. Finally, on the basis of kinetics study and the characterization of Fe NPs before and after Pb(II) and Cd(II) removal, it was proposed that the removal of Pb (II) occurred through both adsorption and chemical reduction, while the removal of Cd(II) occurred through adsorption.

© 2015, Science Press. All right reserved. Graphene oxide (GO), owing to its high specific surface area and oxygen-containing functional groups, has the potential as an efficient adsorbent to remove the contaminants from water, because of the abundant adsorption sites exiting on GO. However, only a few publications about the coadsorption behavior of heavy metal ions and organic pollutants on GO were reported. In this paper, GO was synthesized using the modified hummers method and was used for adsorption of heavy metal, organics and organics-heavy metals coexist pollutants from water. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), fourier transform infrared spectroscopy (FTIR), raman spectroscopy and X-ray powder diffraction (XRD) were employed for characterization of morphology and structure of GO to understand the adsorption mechanism. Methylene blue (MB) and Cu(II) were choosen as the model pollutants for studying adsorption behavior of GO. In mono-pollutant system, the maximum adsorption capacity of Cu(II) and MB was 29.13 mg·g-1 and 424.16 mg·g-1, respectively. While both the adsorption capacity of Cu(II) and MB decreased in Cu(II)-MB binary system, indicating that the competitive adsorption of MB and Cu(II) greatly influences their adsorption behavior. These results revealed that MB has a far greater impact on GO adsorption performance than Cu(II).

© 2015 Elsevier B.V. This study introduced a patented novel methodological system for automatically analysis of Fourier Transform Infrared Spectrometer (FTIR) spectrum data located at 'fingerprint' region (wavenumber 670-800 cm-1), to simultaneously determinate multiple petroleum hydrocarbons (PHs) in real mixture samples. This system includes: an object oriented baseline correction; Band decomposition (curve fitting) method with mathematical optimization; and Artificial Neural Network (ANN) for determination, which is suitable for the characteristics of this IR regions, where the spectra are normally with low signal to noise ratio and high density of peaks. BTEX components are potentially lethal carcinogens and contained in many petroleum products. As a case study, six BTEX components were determinate automatically and simultaneously in mixture vapor samples. The robustness of the BTEX determination was validated using real petroleum samples, and the prediction results were compared with gas chromatography-mass spectrometry (GC-MS).

OBJECTIVE: To investigate the combining therapy which not only have cured effect but also can uphold and improve the NPC patient's immunity function after radiotherapy and chemotherapy. METHOD: 90 cases randomly divided into 3 groups 1. Local group (local injected with IL-2 + radiotherapy + chemotherapy); 2. General group (ivdrip with IL-2 + radiotherapy + chemotherapy); 3. Convention group (radiotherapy + chemotherapy). Checked and observed the immunity function around the immunotherapy and after the radiotherapy and chemotherapy. RESULT: Cellular immunity of 3 groups are lower and humoral immunity are hypetuntion than normal person. After treated with IL-2 the cellular immunity improves but there's no great change of the humoral immunity. The immune status of the immune groups have not obvious change than before radiotherapy, at the same time, the cellular immunity of the convention group cut down and the humoral immunity doesn't change obviously. CONCLUSION: 1. It has some effect to uphold and improve the NPC patient's immunity function to treat with small dosage of IL-2 before radiotherapy and chemotherapy, general treatment is better than local injection; 2. The three therapies have not great influence on the patient's humoral immunity.

Objective: To evaluate the relationship of the polymorphism of LMP2 and LMP7 genes and the phenotype of patients with ankylosing spondylitis (AS). Methods: One hundred and eighteen blood samples were collected from patients with AS and acute anterior uveitis (AAU). HLA-B27 typing was performed and LMP2 and LMP7 amplified fragment length polymorphisms were determined after PCR and digestion with Cfo I restriction enzyme in the study. Results: There was a significantly increased LMP2 BB genotypic frequency in patients with AS + AAU(86.9%) and AAU(87%), compared with controls (53.3%) and AS patients (63.1%) (P<0.05); the odds ratio (OR) relating LMP2 BB and AAU was 5.83, and the OR for AS+AAU was 3.71. No difference was found between adult AS and junior AS and between AS patients with and without extraspinal arthritis. No difference was found in LMP7 genotype. Conclusion: The polymorphism of LMP2 gene is strongly associated with the development of AAU in AS patients and in uncomplicated AAU patients, but not with the age at onset and the type of joints affected.

Ion-exclusion chromatography using a high-capacity sulphonated polystyrene-divinylbenzene (PS-DVB) resin was evaluated for the separation of a range of carboxylic and aromatic acids. The parameters affecting the retention behaviour of these acids were examined in relation to their chemical structure. Results obtained on the ion-exclusion column for the separation of aromatic acids were similar to those obtained on a C18 column. The ion-exclusion column exhibited both the ion-exclusion effect for the separation of hydrophilic carboxylic acids and the hydrophobic interaction for the separation of aromatic acids, which offered the possibility of simultaneous separation of carboxylic and aromatic acids by careful selection of separation conditions such as column temperature and content of organic modifier.

The use of a tungsten oxide sensor for the potentiometric detection of metal ions separated by liquid chromatography is described. Separation of metal ions such as Fe3+, Fe2+, Cu2+ and Pb2+ was performed by ion chromatography using a mobile phase containing 25 mM sodium tartrate/2 mM ethylenediamine at pH 3.8. Calibration plots were linear in the range 0.5 to 3.5 mM. Potentiometric detection was also applied to ion-interaction chromatography. The results showed that separation of metal ions was improved and the detection limits for the test metals in the range of 0.5-5 nmol were obtained in the presence of sodium citrate/1-octanesulfonic acid at pH 3.0. The potentiometric detection described in this article is shown to have advantages in terms of low cost, simplicity and sensitivity.
