Abstract

The technology of selective extraction of molybdenum-99 from nuclear fuel waste for scientific and medical purposes with the use of inorganic sorbents has been developed. Inorganic sorbents based on titanium and zirconium hydroxides with anion-exchange properties were synthesized, their radiation stability and sorption properties with respect to uranium and molybdenum in sulfuric acid solutions were studied. In order to obtain Mo-99 concentrate of required radionuclide purity the sorption behavior of uranium and iodine in the process of Mo-99 extraction from solution fuel was studied. Work on synthesis and study of properties of sorbents based on natural aluminosilicates suitable for decontamination of liquid radioactive waste was continued.
