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

Batch ion exchange tests have been employed to evaluate the ability of SuperLig (R) 644 resin to remove Cs-137 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 lambda value) of similar to 400 based on an initial total cesium concentration of 12.1 mu g/mL. The sorption data also obey the Freundlich and Dubinin-Radushkevich isotherms.
