超声波-光催化氧化降解邻氯苯酚的研究

对超声波一光催化氧化降解邻氯苯酚(2-cp)进行了研究．探讨了溶液初始pH、TiO2投加量、H2O2投加量和溶液初始浓度对2-cp降解率的影响。并对几种不同处理方法降解2-cp的结果进行了对比。结果表明，超声波和紫外光的协同效果明显，在相同的反应时间内，超声波能够明显提高光催化降解2-cp的降解率。超声波和紫外光连用，具有良好的工业应用前景。

Study on technology of sono-photocatalytic degradation of 2-chlorophenol

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.;
