Synergistic Extraction of Th(IV) by Mixtures of HTTA and TBP in Benzene

Abstract
Extraction of Th(IV) from dilute perchloric acid medium by mixtures of HTTA and TBP in benzene medium was studied. The species Th(TTA)4 TBP was found responsible for the observed synergism. Equilibrium constants for the extraction equilibria involved are log KA = 2.25, log KAB = 6.88, and log βAB = 4.63.
