水合氧化锆的研制

Development of the Hydrous Zirconium Oxide for Radioactive Isotope Generators

本文介绍了用于放射性同位数发生器的无机离子交换剂水合氧化锆(HZO)的生产工艺条件(沉淀方法、洗涤体积、烘干时间、烘干温度、树脂粒度及保存时间等)和影响水合氧化锫吸附容量的各因素。本工艺制取的水合氧化锆,其工作吸附容量为29mg(Sn)/g(HZO)、最大吸附容量为36mg(Sn)/g(HZO)。用此水合氧化锆能制备3.7GBq 以上的高活度^(113m)In 发生器和品质优良的37GBq 以上的高活度凝胶型^(99m)Tc 发生器。

This paper describes a lot of investigations for the influence of the pro-duction conditions on the adsorption capacity of hydrous zirconium oxide(HZO)using for radioactive isotope generators.A better production processof the HZO has been obtained through these investigations.The working ad-sorption capacity is 29 mg(Sn)/g(HZO)and the maximum a(?)sorption capacityis 36mg(Sn)/g(HZO)for HZO.Indium-113m generator with over 3.7GBq andhigh radioactive gel Technetium—99m generator with best quality and over37GBq have been produced by the HZO.
