A new method for separation of 131I, produced by irradiation of natural uranium

Separation of 131I from natural uranium fission product mixtures has been accomplished by sorbing the 131I on special platinum–charcoal sorbent and desorbing by buffer solution (NaHCO3+Na2S2O3). High radiochemical and chemical purity is obtained by this method. Important parameters such as temperature, distillation rate, sorbing and desorbing rates and 131I separation yields have been investigated.
