Abstract

The distribution data of uranous nitrate, uranyl nitrate and nitric acid inU(IV)-U(VI)-HNO_3/30% TBP kerosene system are systematically determined at25±0.5℃. A total of 187 sets of experimental data is collected under variousconcentrations of species in the system. The concentrations of different speciesare as follows: 5--50g/1 in U(IV), 10--150g/1 in U(VI) and 0.4--4 mol/lin HNO_3. The calculation of material balances indicated that those data arecredible.
