研究了U(Ⅳ)在分离的有机相(30％TBP-煤油)中、在两相振荡混合和逆流萃取过程中的稳定性。通过单级反萃实验研究了有机相中钚浓度、铀浓度,反萃剂的酸度和肼浓度,U(Ⅳ)用量(M_(u(Ⅳ))/M_(Pu)对钚反萃率的影响。通过串级实验研究了在1B槽工艺条件下,M_(u(Ⅳ))/M_(Pu)和U(Ⅳ)加入位置,反萃剂酸度和相比等条件的变化对铀钚分离的影响。给出了铀和钚的净化系数。
The stability of U (Ⅳ) in the separated organic phase (30% TBP-kerosene) was studied in two-phase oscillating mixing and countercurrent extraction. The plutonium concentration, uranium concentration, stripping agent acidity and hydrazine concentration, U (Ⅳ) dosage (M u (Ⅳ)) / M Pu in the organic phase were studied by single stage stripping experiments. The effects of M_ (u (Ⅳ)) / M_ (Pu) and U (Ⅳ) addition sites, the acidity and the ratio of stripping agent on the separation of uranium and plutonium The effects of uranium and plutonium are given.
