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。
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.
