Abstract

The solutions of carrier-free125mTe(VI) have been prepared by oxidizing125mTe(IV) with bromine. Using carrier-free125mTe(VI) as a tracer, the effects of pH, NaCl concentration, and tellurium(VI) concentration on the adsorption and colloidal properties of tellurium(VI) in NaCl solution have been studied. It has been found that traces of tellurium(VI) are adsorbed on filter paper and show colloidal behavior in the basic region. A method has been devised for the separation of carrier-free125mTe from its parent nuclide125Sb, based on the adsorption properties of125mTe(VI) in basic solutions.
