Description
The extraction of TBP (tributyl phosphate)-TRPO (mixed trialkyl phosphine oxide)/kerosene for HNO3, UO22+, Pu(IV), Am3+, TcO4- and Cs+ is conducted. The distribution ratios of HNO3 and these ions are determined. The loading capacities of the binary system for both UO22+ and HNO3 are studied. The experiments demonstrate that the binary system has no synergistic-extraction effect for Am3+ and two different effects for TcO4-. The Pu(IV) which extracted in the binary system can be stripped by 0.6 mol/L H2C2O4 efficiently
