Outline of Final Research Achievements

The purposes of this study are establishment of plural-phase extraction system and development of suitable extractant. The isooctane/water/1-Butyl-3-methylimidazolium Bis(trifluoromethanesulfonyl)imide/perfluorononane system was successfully formed a stable four phase system. To establishment of plural-phase extraction system, novel extractant which has quantitative extraction/back extraction ability in ionic liquid system was synthesized. The organic solvent (containing PC-88A)/water/ionic liquid (containing synthesized extractant) extraction system was enabled separation of Sc, La, and Eu into organic phase, aqueous phase, and ionic liquid phase, respectively.
