摘要

In current salt-free flow sheets, U(Ⅳ) is used as a reduc- tant in reductive partitioning of U-Pu. Because U(Ⅳ)-tri-n- butylphosphate (TBP) solvate has a low solubility in the organic phase, quantitative knowledge of U(Ⅳ) distribution behavior is important. Published data on U(Ⅳ) distribution between an aqueous nitric acid and 30/100 TBP-dodecane biphasic sys- tem at 298.15K is analyzed, and an empirical model is re- ported. Performance of this model is compared with one earlier published model.
