DETERMINATIONS OF THE EXTRACTION EQUILIBRIUM DATA OF U(VI), U(IV) AND HNO_3 IN UO_2(NO_3)_2-U(NO_3)_4-HNO_3/30% TBP KEROSENE SYSTEM

  • 摘要: 在下列条件下,系统地测定了U(VI)-U(IV)-HNO_3/30% TBP-煤油体系中各溶质的萃取平衡数据187组。条件为:25±0.5℃;原始水相中U(IV)浓度为5—50g/l;U(VI)浓度为15—150 g/l;肼浓度为 0.1mol/l; HNO_3 0.4—4 mol/l。经物料衡算检验,数据基本可靠,可用于萃取平衡的数学描述。

     

    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.
