Abstract

Extraction of americium(III) ions with ionizable dialkylphosphoric or dialkylphosphinic acids from aqueous solutions to the ionic liquid, l-decyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide have been investigated. The results are compared with the analogous traditional molecular solvent systems and show similar patterns for the distribution ratios in each system. Studies indicate that the metal ion coordination environments, elucidated from EXAFS and UV-visible spectroscopy measurements on Nd ³⁺ and Eu³⁺ respectively, as stand-ins for Am ³⁺, are equivalent in the two systems with coordination of the metal ion with three extractant dimers forming a neutral complex. Extraction equilibria and metal coordination studies demonstrate that with these complexants, the extraction mode and metal coordination environment are conserved in the IL and molecular organic solvent systems.
