Abstract

A new method microwave assisted UV electrodeless discharge lamp photocatalysis system(MW/UV/P25)is used for the treatment of 4CP simulated wastewater. The degradation rate of 4CP is up to 82.85% and the increase of concentration of Cl- is up to 7.95 mg/L after 120 min of reaction. The degradation efficiency is influenced by pH value of the suspensions, aerating N2 gas, varying light intensity etc, addition of H2O2 oxidant can improve the degradation rate. The degradation of 4CP under MW/UV/P25 accords with the first grade kinetics equation.
