摘　　要：对超声波-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值、TiO2投加量、H2O2投加量和溶液初始浓度对邻氯苯酚降解率的影响。并对几种不同处理方法降解邻氯苯酚的结果进行了对比。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邻氯苯酚的降解率。超声波和紫外光连用,具有良好的工业应用前景。Sono - phontocatalytic degradation of 2 - chlorophenol was introduced.The effects of pH,TiO2 quantity, H2O2 quantity and concentration of 2 - chlorophenol on the degration efficiency of 2 - chlorophenol were studied. And the detradation efficiency of 2 -chlorophenol by several different ways were compared. The results showed that the corporation of ultrasonic wave and ultraciolet had great effect on the degradation of 2 - chlorophenol. Ultrasonic wave could greatly increase the photocatalytic degradation rate of 2 - chlorophenol during the same reaction time. So ultrasound technology combined with ultraviolet had enormous application advance in industry.
