Column behaviour of resorcinol-formaldehyde polycondensate resin for radiocesium removal from simulated radwaste solution

Abstract

The selective removal of radiocesium was studied using a column filled with resorcinol-formaldehyde polycondensate resin (RFPR) prepared in the laboratory. The feed to the column was a simulated alkaline radioactive waste solution with high salt load of spent fuel reprocessing plant origin. Repeated loading-elution-regeneration cycles were conducted to determine reproducibility of breakthrough behaviour. The breakthrough data were correlated with batch equilibration data on cesium uptake. The quantitative elution of sorbed radiocesium was also confirmed.
