Abstract

Radio-chromatography was conducted by using the astatine radionuclides 209,210,211At produced in the 7Li induced reaction of 209Bi. The speciation of dissolved astatine chemical species of astatide (At−), astatate (AtO3−) and perastatate (AtO4−) was carried out by thin layer chromatography on silica gel with an ethanol/water solution. Amounts of the astatine species varied with concentrations of oxidizing and reducing reagents, potassium periodate, sodium sulfate and hydrazine hydrate. The oxidation–reduction reactions between At−(−I) and AtO3− (V) were found to form volatile At0 (0) and release it from a silica gel thin layer in the development.
