Photocatalytic Degradation of Phenol

Article

Abstract

In this study photocatalytic degradation of phenol in thepresence of UV irradiated TiO2 catalyst andH2O2was investigated. Effects of TiO2 andH2O2concentrations and pH on photocatalytic degradation were examined. The rate constants for photocatalytic degradation wereevaluated as a function of TiO2 and H2O2 concentrations and pH of the solution. It was found thatphotodegradation is an effective method for the removal of phenoland disappearance of phenol obeyed first order kinetics. The amount of CO2h produced during photocatalytic degradation wascorresponding to the complete mineralization. Photodegradationcan be an alternative method for the treatment of phenol containing wastewaters.
