摘要：
A chelating resin was synthesized by incorporating thiosemicarbazide into Amberlite IRC-50, a weakly acidic polymer. Astatine radionuclides produced by (-alpha)irradiating bismuth oxide were separated using the newly synthesized chelating resin. The resin showed high selectivity for astatine. The adsorbed astatine was recovered using 0.1 M EDTA at pH similar to 10. (C) 2004 Elsevier Ltd. All rights reserved.
