Quantifying the Hofmeister Series in Complex Electrolytes

Specific ion effects are ubiquitous and contribute greatly to the complexity of solutions. Within this complexity, the Hofmeister series orders ions according to their relative strength in bringing about a large range of effects and is seen in a wide variety of systems. Our recent research led to the development of a quantum chemical parameter that, for simple electrolytes, was capable of quantifying the Hofmeister series and specific ion effects.

This project will extend our recent work in this field by developing analogous parameters for complex electrolytes - that is electrolytes that contain multiple salts, more complex ions, solvent mixtures and a variety of other solutes. These parameters will inform a wider collaboration with experimental partners at The University of Newcastle, the Australian National University and Flinders University that aims to comprehensively understand specific ion effects in complex electrolyte solutions containing multiple different ions (as found in biological systems), different solvents and solvent mixtures (as used in solvent extraction and power storage technologies), very high salt concentrations (important in crystallisation, deep eutectics and repurposing waste water streams) and in the presence of exotic ions (as used in battery technologies and for example the ions that comprise ionic liquids).
