>Impurities are separated from plutonium solutions by means of TTA (thenoyltrifluoroacetons) extractions. Plutorium in hydrochloric acid solution is reduced to the trivalent state with hydroxylamine, and some tmpurities nre extracted into hexone or a solution of TTA in hexone. The organic phase is removed, and the pltonium in the aqueous phase is oxidized to the tetravalent state with nitric acid. The plutonium is then extracted into TTA in hexone, and most of the impurities remain in the aqueous phase. The organic phase of the plutonium(III) extraction and the aqueous phase of the plutonium(IV) extraction are then analyzed by the copper spark spectrographic method. Investigations of several variables which affect the extraction are described. Analytical results by this methods ane coanpared with those by the carrier distillation and cupferron extraction methods. The distribution of over 60 elements in these extractions is listed. (auth)
