Sorption of Cs, Sr, and Co from a solution by a composite sorbent (ClSZ) based on zeolite depending on the activation temperature

AbstractStudy of the influence of zeolite activation temperature on the sorption of a mixture of remove radionuclides Cs, Sr, Co. The activation temperature ranged from 150 to 450  °C. It was found that temperature activation did not lead to changes in clinoptilolite structure. After thermal activation, in all the considered temperature ranges, the sorption properties of clinoptilolite decreased by 15%. For composite sorbents, activation at 150 °C was the most effective. In this case, composite sorbents exhibited complex interactions with the mixture of radionuclides. Cs sorption decreased by 7%, Sr sorption increased by 1%, and Co sorption increased by 10–12%.
