摘要

Present study explores the extraction mechanism of ²¹¹At of 7.21 h half-life used in targeted alpha-ray therapy. We produced ²¹¹At and ²¹⁰At nuclides to investigate the extraction mechanism with diisopropyl ether (DIPE) and At species in the solvent. Thin-layer chromatography results showed that At cation species increased with increasing HCl concentration and the rate of At extraction into DIPE.
