A satisfactory coprecipitation of Pu(IV) and separation of all elements except thorium are achieved with butylrhodamine nitrate at 1: 1 x 10/sup 10/ Pu(IV) dilution. The precipitation of Ce(IV) Is eliminated by the preliminary transition Ce(IV) yields Ce(III). The amount of uranium carry-over is reduced by U(IV) yields U(VI). Following four precipitations, 80% of the plutonium can be separated with only 0.0025% uranium carry-over from the initial mixture of Pu(IV). With pH approximately 5 to 7 the method can also be utilized for coprecipitation of Pu(III) in dilute solutions. The selectivity of precipitation in the latter case is worse than with Pu(IV).
