本工作是为测定铀的裂变产额而建立的组分离程序。在确定了铀靶的溶解方法和同位素交换条件下,研究了铀及其裂变产物在HNO_3-阴离子交换树脂和HCl-阴离子交换树脂上的吸附和解吸行为,选择并确定了这些元素在该体系中的吸附和解吸条件的基础上,建立了HNO_3-阴离子交换和HCl-阴离子交换为主的组分离程序。整个程序可将克量铀、几百毫克铝(包壳材料)和裂变产物分成十一组,各元素的回收率为60—95%。
This work is a group separation procedure established to determine the fission yield of uranium. The adsorption and desorption behaviors of uranium and its fission products on HNO_3-anion exchange resin and HCl-anion exchange resin were studied under the conditions of uranium target dissolution and isotope exchange. The selection and determination of these elements in the system Based on the adsorption and desorption conditions, a group separation program based on HNO 3 anion exchange and HCl anion exchange was established. The entire program can be grams of uranium, hundreds of milligrams of aluminum (cladding material) and fission products into eleven groups, the recovery rate of 60-95% of the elements.
