Popis:	Sorption of Pu4+, UO 2 2+ , NpO 2 + , Am3+, and Eu3+ ions on S-957 cation exchanger from 2–7 M HNO3 solutions was studied. The following selectivity series was obtained: Pu4+ > UO 2 2+ > NpO 2 + > Am3+ ≈ 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.
