Abstract

In order to obtain pure radionuclides of ¹³¹I, the adsorption-chromatographic separation of the iodine-131 radionuclide from the tellurium target material was studied. In the experiments, we used aluminum oxide impregnated with silver nitrate as a sorbent. The conditions for the sorption of the ¹³¹I radionuclide on a modified sorbent in an alkaline medium and it’s desorption by solutions of Na₂S and Na₂S₂O₃ were studied.
