Description

The back-extraction of Am3+, Pu(IV), UO22+ and TcO4- with high concentration nitric acid, oxalic acid, sodium carbonate, ammonium carbonate respectively from different 30% TRPO/kerosene systems are studied. The emulsification phenomenon during the back-extraction of UO22+ with sodium carbonate is investigated. The infrared sorption spectra and the pyrography of these TRPOs are compared. The results show that different TRPOs have same kinds of base groups, but have different constitution of these base groups
