摘要
在３０％ＴＢＰ（煤油）／ＵＯ２（ＮＯ３）２－ＨＮＯ３体系中，测定了一定铀浓度和酸度下Ｃｅ（Ⅳ）的分配系数，研究了Ｃｅ（Ⅳ）在有机相和Ｃ（Ⅲ）在水相的稳定性，在两相接触情况下测定了Ｕ（Ⅳ）对Ｃｅ（Ⅳ）的还原速度。并与钚在同样条件下的相关性质进行了比较。
In the system of 30% TBP(OK)/UO2 (NO3)2-HNO3 with certain concentrations of uraniumand nitric acid we have determined the distribution coefficients of Ce(Ⅳ). And also the stabilities of Ce(Ⅳ) in organic phase and Ce(Ⅲ)in aqueous phase were investigated. In addition, we measured the reduction velocities of Ce(Ⅳ)under the action of U(Ⅳ) and the mixing condition of two phases.The obtained results are compared with the relative performance of plutonium underthe same conditions.
