【Abstract】 Sono-photocatalytic degradation of 2-chlorophenol was studied. The effects of pH, TiO-2, H-2O-2 and concentration of 2-chlorophenol on the degradation efficiency of 2-chlorophenol were analyzed. The degradation efficiency of 2-chlorophenol by several different ways was compared. The results show that the corporation of ultrasonic wave and ultraviolet had great effect on the degradation of 2-chlorophenol. Ultrasonic wave can greatly increase the photocatalytic degradation rate of 2-chlorophenol during the same reaction time. So ultrasound technology combined with ultraviolet has enormous application advance in industry.;更多还原
