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。
After the experimental screening, the ~ (14) Ti- ~ (44) Sc generator was prepared for the first time using Polyan HT as adsorbent and HCl- (NH1) 2C2O4 as eluent. The separation factor of ~ (44) Sc to ~ (44) Ti was more than 10 ~ 6, the recovery of ~ (44) Sc was about 80%, and the column could repeatedly wash ~ (44) Sc 200 times.
