Radiochemical sequential separation of Tl (I), In (III) and Sr (II) from a mixture by adsorbing on synthetic inorganic ion-Exchangers

The present work aims at radiochemical sequential separation of Tl (I), In (III) and Sr (II) from a mixture by employing synthetic inorganic ion-exchanger. Zirconium phosphosilicate and zirconium phosphate has been synthesized and their composition has been determined.²⁰⁴Tl, ^114mIn and ⁸⁵⁺⁸⁹Sr have been used as tracers for optimizing the ideal conditions in the adsorption. Reproducibility of maximum adsorption at ideal conditions were found as 91.67 ± 2.08% for Tl (I) and 94.48 ± 2.8% for In (III) on zirconium phosphosilicate whereas 91.30 ± 2.0% for Sr (II) on zirconium phosphate. The radiochemical purity has been determined by gamma ray spectra or aluminium absorption curve after sequential separation.
