钚及其裂变产物钯 、银 、镉 、锡 、锑 、锆的系统分离方法

描述了钚及其6种裂变产物钯、银、镉、锡、锑、锆的系统分离方法：在强碱性阴离子交换树脂柱上将盐酸介质的辐照靶溶解液中的这些元素分为5组，然后再针对各组目标元素进行分离和纯化，可简便快速地从同一份靶溶解液中分离以上7种元素。采用辐照铀靶对分离方法进行了验证，结果表明，分离流程对6种裂变产物的化学回收率均大于70%，对γ谱仪测量干扰的主要核素去污因子均大于1.0×10³，可满足²³⁹Pu裂变谷区核素裂变产额测量对化学分离的要求。

A Systematic Separation Procedure for Plutonium and Its Fission Products Palladium,Silver, Cadmium,Tin, Antimony and Zirconium

In this work, a process of systematic separation for Pu and its fission products Pd, Ag, Cd, Sn, Sb and Zr was established. Firstly, these elements in the solution of hydrochloric acid medium were divided into five groups on strong basic anion resin. Then the target elements were separated and purified for each group. The method is simple, rapid and can separate the above 7 elements from the solution of one target. The separation method was verified by using irradiated uranium target. The results show that the chemical yields of the separation process are more than 70% for the 6 fission products, and the decontamination factors of the main interfering nuclides for the gamma spectrometry measurement are more than 1.0×10³. The separation process can meet the requirements of chemical separation for fission yield measurement of valley nuclides from²³⁹Pu fission.
