摘要
研究了超声辐照技术去除模拟废水中的邻二氯苯的效果和影响因素,包括超声电功率、初始浓度、溶液初始pH值、空气曝气以及自由基抑制剂等;研究结果表明,超声辐照去除邻二氯苯主要以空化泡内的高温热解为主,并分析了邻二氯苯超声去除的途径和机理。
The mechanism of ultrasonic irradiation degradation of ortho-chlorobenzene in aqueous solution and factors that influence the reaction including ultrasonic electronic power, initial concentration, initial pH, air aeration and free radical scavengers were studied. Results showed that ortho-chlorobenzene was mainly dissociated by pyrolysis under instant high temperature and high pressure in the cavitation bubbles.
