UO_2(NO_3)_2-HNO_3-H_2O/30％(体积)TBP-240号煤油体系中铀、酸分配数据的测定

DETERMINATIONS OF THE DISTRIBUTION DATA OF URANYL NITRATE AND NITRIC ACID IN UO_2(NO_3)_2-HNO_3-H_2O/30% (VOL. )TBP KEROSENE SYSTEM

摘要: 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。

Abstract: Systematic determinations, of the distribution data of uranyl nitrate and nitric acid in UO2 (NO3)2-HNO3-H2O/30% (Vol. ) TBP-kerosene system were made. The concentrations of the 193 experimental points cover from . 1.0.×10-6 to 1.0 mole in uranyl nitrate and from 1.0×10-3 to 6.1. mole in, nitric acid. Among these experimental points 154 were obtained at 20℃ the others at 30°, 50° and 70℃, 13 for each temperature.. The material balances show that these data are substantially credible.
