Degradation kinetics of dichloromethane in water were investigated in a rectangular quartz cell under combination of UV irradiation and hydrogen peroxide (H2O2) addition. The presence of H2O2 not only enhanced the degradation rate of dichloromethane but prevented the formation of other chlorinated organic compounds as transient intermediates to mineralization. Since H2O2 was consumed by UV at a much higher rate than dichloromethane, it was found that the consecutive addition of H2O2 was highly effective to maintain high-rate degradation of dichloromethane. When 2,000 mg·l-1 of H2O2 was added every 5 min, the decomposition rate of 1,500 mg·l-1 dichloromethane exhibited 9.3 times higher than that of one-time addition of H2O2. Moreover, we successfully demonstrated that the degradation rate of dichloromethane was almost proportional to the square of incident light intensity.
