Radiation-induced degradation of aqueous 2-chlorophenol assisted by zeolites

This study aims to demonstrate that zeolite has the potential to increase the efficiency of radiolysis treatment of aqueous organic pollutants by concentrating the pollutants into the zeolite's pores. Using 2-chlorophenol (2-ClPh) as a model compound, we determined the high performance to be displayed by a mordenite-type zeolite (HMOR), which has a high silicon-to-aluminum ratio. HMOR adsorbed far more 2-ClPh than the other zeolites used in this study. We observed a significant increase in the radiolytic degradation efficiency of 2-ClPh in the presence of HMOR. Evidence shows that the high concentration of zeolite-adsorbed 2-ClPh facilitates radiation-induced degradation.
