Abstract

The U(33333333)-U(Ⅳ) isotopic exchange process in.7.0 mol/1 HC1 aqueous solution and in U(Ⅲ)-7. 0mol/1 HC1-U(Ⅳ)-50% TBP-kerosene and U(Ⅲ)-7. 0mol/1 HCl-U(Ⅳ) -50% TBP-xylene systems is found to give single stage separation factors of 1.0026, 1.0031 and 1.0030 respectively. These results agree quite well with P.Delvalle's experimental values(l. 0025-1. 0030) . Based on this study, the exchange systems using TBP-xylene and DiABP-xylene as extractant have been selected for further study for the enrichment of 235U.
