无机基体聚锑酸~(44)Ti-~(44)Sc发生器

AN INORGANIC-PACKED ~(44)Ti-~(44)Sc RADIOISOTOPE GENERATOR

摘要: 经过实验筛选,第一次采用聚锑酸Polyan HT为吸附剂,HCl-(NH_1)_2C_2O_4为淋洗剂,制备了~(14)Ti-~(44)Sc发生器。~(44)Sc对~(44)Ti的分离因子大于10~6,~(44)Sc的回收率为80％左右,柱子可反复淋洗~(44)Sc 200次。

Abstract: A crystal form of polyantimonic acid (Polyan HT) is first selected as adsorbent for ~(44)Ti~(44)Sc gen erator, and HCI-(NH_4)_2C_2O_4 is selected as eluent. The separation factor of ~(44)Sc from~(44)Ti is more than 10~6 with about 80% yield of ~(44)Sc, and the generator can be used to elute ~(44)Sc for 200 times.
