Extraction mechanisms in Ionic Liquid (IL) based separations systems for metal ions are potentially much more complex that those with simple organic solvents as extracting phases. This arises from the potential for either, or, both cations and anions from the IL to contribute in the extraction processes. In contrast to organic extracting phases, ionic liquids can not necessarily be considered to be passive carrier fluids. Solvent extraction and cation, anion, or sacrificial ion exchange mechanisms have been observed, and the significance of each varies depending on the nature of the ionic liquid components and of the complexants used. Recognition and application of this knowledge allows potential control of the complexation and extraction mechanisms.
