The characteristics of the TBP/XAD-4 resin on the separation of uranium, neptunium, plutonium, americium and fission products have been studied. The capacity of the TBP/XAD-4 column was compared with the maximum capacity determined by batch experiment using uranium. On the basis of distribution ratios of the actinide elements and fission products, the separation procedure of these elements was constructed by combining extraction chromatography in the TBP-HNO3 system and the redox reactions of the actinide elements.
