| Outline of Final Research Achievements |
In extraction of metal ions using ionic liquids as extraction solvents, effect of various ionic matrices in the aqueous phase on the extraction behavior was investigated. In ionic liquid chelate extraction, formation of ternary complex of a metal ion, a chelator and an anionic monodentate ligand matrix sometimes resulted in extraction enhancement of the metal. In cation-exchange extraction using neutral polydentate ligands, the ionic liquid cation and/or anion dissolved in the aqueous phase strongly affected the metal extraction behavior.
