| Abstract: | Extraction by benzene solutions of TBP of carrier-free90Y(III) from mixed aqueous-organic nitrate and perchlorate solutions was studied with special respect to the S-shaped DY versus acid concentration plots observed in aqueous systems. The presence of organic solvents in the aqueous phase enhanced
the extraction of Y(III) and also influenced the shape of the DY vs. acid concentration plots in that the minimum was shifted towards lower acid concentration, became less pronounced, and
eventually vanished completely. |
