对UO_2(NO_3)_2-HNO_3-H_2O/30％(体积)TBP-240号煤油体系系统地测定了平衡水相UO_2(NO_3)_2浓度为1.6×10~(-6)-1.0M,HNO_3浓度为1.0×10~(-3)-6.1M范围内的铀、酸分配数据193组,其中20℃数据154组,30,50和70℃数据各13组。经物料衡算检查,证明数据基本可靠。
The concentration of UO_2 (NO_3) _2 in the system of UO_2 (NO_3) _2-HNO_3-H_2O / 30% TBP-240 kerosene was measured systematically. The concentration of HNO_3 was 1.6 × 10 -6 -6.0, For the uranium and acid distribution data in the range of 1.0 × 10 -3 -6.1 M, 193 groups were assigned, of which 154 were data at 20 ℃ and 13 were data at 30, 50 and 70 ℃ respectively. The material balance check to prove that the data is basically reliable.
