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

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.
