| Abstract: | 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. |
