Removal of cesium from alkaline waste solution: Part I – Batch ion exchange study

Abstract

Summary Batch ion exchange tests have been employed to evaluate the ability of SuperLig® 644 resin to remove 137 Cs from highly alkaline nuclear waste solution. The batch sorption data indicated the SuperLig® 644 resin has a relatively high sorption affinity for cesium with a predicted number of bed volumes required to reach 50% breakthrough in a column operation (generally known as λ value) of ∼400 based on an initial total cesium concentration of 12.1 μg/mL. The sorption data also obey the Freundlich and Dubinin–Radushkevich isotherms.
