放射性Cs同位素是裂变产物分析、后处理工作中较为关心的核素,本工作主要针对较短寿命Cs同位素的分离,开展可用于较高流速下进行Cs分离的离子交换剂的制备方法及其性能的研究。采用溶胶一凝胶法制备了大颗粒zrP-AMP复合离子交换剂,通过磷酸锆(ZrP)凝胶包裹磷钼酸铵(AMP),并对凝胶干燥时间和温度进行控制,使 Radioactive Cs isotopes are the nuclides of interest in the analysis and post-treatment of fission products. This work mainly focuses on the separation of Cs isotopes with shorter life span and the preparation of ion exchangers for their separation at higher flow rates and their performance Research. A large particle zrP-AMP complex ion exchanger was prepared by sol-gel method. Ammonium phosphomolybdate (AMP) was encapsulated by zirconium phosphate (ZrP) gel and the gel drying time and temperature were controlled.
