Photocatalytic degradation of phenol over TiO2 powder: The influence of peroxomonosulphate and peroxodisulphate on the reaction rate
Source abstract
Abstract
Abstract Advanced oxidation processes (AOPs) have been developed as an emerging technology for treating hazardous organics in wastewater and groundwater. In the present study, the effect of oxidants [peroxomonosulphate (PMS) and peroxodisulphate (PDS)] on the photocatalytic oxidation of phenol on illuminated TiO 2 surfaces has been investigated. The efficiencies of these oxidants on photocatalytic degradation of phenol are compared with that of H 2 O 2 . The experimental results indicate that these oxidants exhibited enhanced rates of mineralization of phenol. A reaction mechanism, involving the generation of both hydroxyl radicals and sulphate radicals, was proposed.
