超声辐照降解水中氯苯的研究

摘要

研究了超声辐照工艺技术降解水中氯苯的效果和影响因素，包括声强、溶液pH值、初始浓度、溶解气体和自由基清除剂，并探讨了氯苯超声降解的机理。试验结果表明氯苯的超声降解主要在空化泡内热解，降解效果好。%The mechanism of the ultrasonic irradiation accelerating degradation of chlorobenzene in aqueous solution and the factors that influence this reaction were studied. For this course the sound intensity, the pH value, the initial concentration of the dissolved gases in the solution and the applied free radical scavengers are included. The results show that the chlorobenzene mainly dissociates by thermolysis in cavitation bubble.
