At-211 was produced in the(209)Bi(He-4, 2n)At-211 reaction. The yield was separated from the irradiated bismuth target by a simple method, based on dry distillation. The optimized conditions of the method were studied by monitoring the astatine radioactivity with gamma-ray spectrometers. The no-carrier-added(211)At solutions were prepared with eluents, namely distilled water, ethanol, methanol, or chloroform. Generally, the recovery yields obtained with the utilization of 1.6 mL of the eluent were 26-75%. The prepared(211)At solutions were subjected to thin-layer chromatography and high-performance liquid chromatography to identify the chemical species present.
