Sorption of Pu4+, UO22+, NpO2+, Am3+, and Eu3+ ions on S-957 cation exchanger from 2-7 M HNO3 solutions was studied. The following selectivity series was obtained: Pu4+ > UO22+ > NpO2+ > Am3+ approximate to Eu3+. The static and dynamic capacities of the sorbent for Pu were determined, and the eluent composition for the efficient desorption was chosen. The possibility of separating Pu(IV)-Am(III) and Pu(IV)-Np(V) pairs on the sorbent in the column chromatography mode was demonstrated.
