| Outline of Final Research Achievements |
We studied effect of adsorption and condensation by zeolites on radiation-induced degradation of chlorinated aromatic compounds. This study aims to demonstrate that the solid-phase extraction using zeolites has potential for improving the efficiency of radiolytic treatments of aqueous organic pollutants. Among three zeolites examined in this study, a mordenite type zeolite (HMOR) that has a high Si to Al ratio exhibited high performance as the matrix for the degradation of chlorinated aromatics. The irradiation of HMOR induced degradation of adsorbed chlorinated aromatics and produced chloride ion. We found a significant increase in chloride ion production by HMOR. The increased chloride ion production indicates that the high concentration of adsorbed 2-ClPh led to effective use of the adsorbed energy of HMOR.
