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 article describes the production process conditions (precipitation method, washing volume, drying time, drying temperature, resin particle size and storage time, etc.) of inorganic ion exchange agent hydrated zirconia (HZO) for radioisotope generator and the influence of hydration Oxidation 锫 adsorption capacity of the various factors. The hydrated zirconia prepared by the process has the working adsorption capacity of 29 mg (Sn) / g (HZO) and the maximum adsorption capacity of 36 mg (Sn) / g (HZO). With this hydrated zirconia, a high activity ~ (113m) In generator with a capacity of 3.7 GBq or more and a high activity gel ~ 99m Tc generator with a high quality of 37 GBq can be prepared.
