Abstract: Objective: The objective was to study the leaching behavior of Co2+ and Cd2+ ions from stannic antimonate, cobalt and strontium doped stannic antimonate at different conditions. Methodology: The total capacity of stannic antimonate and its dopants cobalt and strontium stannic antimonates for Co2+ and Cd2+ ions were investigated before and after irradiated at different doses. The crystallite size and lattice strain of stannic antimonate and its dopants cobalt and strontium stannic antimonates after saturation with Co2+ and Cd2+ ions were determined at different irradiation doses. The surface area values of stannic antimonates and its dopants were measured using BET-technique. Results: The leach rate values of Co2+ ion from stannic antimonate saturated with cobalt and cobalt stannic antimonate at different irradiation doses were determined and show the leach rate values of Co2+ ion from cobalt stannic antimonate lower than those obtained from stannic antimonate saturated with cobalt. Conclusion: The leach rate of ion was decreased by doping of the same ion with the ion exchanger and increasing the radiation dose that exposed to the exchange materials from 0-100 kGy.
