Abstract

Photocatalytic degradation of dicofol was investigated on TiO2 nano particles (TiO2-NPs) under UV light irradiation. It was shown that dicofol could be completely degraded into inorganic chloride ion under the condition of 0.25 mg/mL TiO2-NPs, 2 h irradiation of 400 W high pressure mercury lamp with a wavelength of 365 nm and air at a rate of 100 mL/min. The effects of the experimental conditions, including the amount of TiO2-NPs, irradiation time and the intensity of light, were studied. The apparent photodegradation rate constant was 0.167/min under the optimal condition. The photocatalytic degradation mechanism of dicofol was also discussed.
