Synergistic extraction of Pu(IV) by mixtures of HTTA with TBP and DBBP

Journal Article · · Sep. Sci. Technol.; (United States)
The synergistic extraction of Pu(IV) from perchloric acid medium by mixtures of thenoyltrifluoroacetone (HTTA) and the neutral donors tri-n-butylphosphate (TBP) and dibutyl butylphosphonate (DBBP) using benzene and cyclohexane as diluents was investigated by different solvent extraction methods. With TBP, the adduct responsible for synergism was found to be Pu(TTA)/sub 4/ TBP. With DBBP, in addition to Pu(TTA)/sub 4/ DBBP, it was indicated that more species containing perchlorate ion are involved in the extraction. The adduct formation of Pu(TTA)/sub 4/ with DBBP in benzene was also investigated by spectrophotometry. The equilibrium constants for several equilibria involved were obtained.
