Synergistic solvent extraction of Pu(IV) from nitric acid medium by mixtures of thenoyltrifluoroacetone (HTTA) and tri-n-octylphosphine oxide (TOPO) in benzene was investigated by a method developed for such studies. The species involved in the extraction were identified as Pu(NO/sub 3/)/sub 4/.2TOPO, Pu(NO/sub 3/)/sub 3/(TTA).2TOPO, Pu(NO/sub 3/)/sub 2/(TTA)/sub 2/.TOPO, and Pu(NO/sub 3/)(TTA)/sub 3/.TOPO. The concentration equilibrium constants for the extraction of all the suggested species from the 1.0 M nitric acid were calculated from the data obtained, and the concentration equilibrium constants for their formation in the organic phase were estimated. 1 figure, 4 tables.
