Abstract

The problem of reprocessing of used ion-exchange resins with a polystyrene-divinylbenzene matrix by oxidative degradation using the Fenton process is considered. The kinetics of the process was studied in the presence of 5–25% solutions of H₂O₂ containing catalytic additives of copper(ii;) and iron(ii;,iii) salts. Electron microscopic studies revealed characteristic changes in the surface morphology and granule shape of the ionexchange resins during oxidative decomposition.
