摘要
研究了 3 0 %TBP -煤油在不同的硝酸 -草酸混合溶液中对Np ,Pu各价态的萃取分配 ,在HNO3-H2 C2 O4 体系中 ,通过加入HNO3抑制草酸的电离 ,从而基本上消除草酸对 3 0 %TBP -煤油萃取Np ,Pu的影响。根据所得数据研究了 3 0 %TBP -煤油萃取分离Np ,Pu的工艺流程 ,并给出了各工艺参数。
The separation of Np,Pu has been studied in mixed H 2C 2O 4 HNO 3 30% TBP kerosene. In condition of high acidity,the dissociation of H 2C 2O 4 is inhibited,and the influence of H 2C 2O 4 upon Np,Pu extraction ability by 30% TBP kerosene as extractant has been eliminated in certain degree. According to the difference of HNO 3 and H 2C 2O 4 acidity, Np,Pu extraction contribution ratios of 30% TBP kerosene are given, on the basis of it,one technological process of separation of Np,Pu with extraction of 30% TBP kerosene and each technological parameter are recommended.
