| 摘 要： | 在超声波作用下水中微量亚甲基蓝可有效降解，降解动力学符合一级反应，亚甲基蓝超声降解速率随初始浓度的升高而降低，随介质温度的下降而升高．亚甲基蓝在酸性和碱性条件下的降解速率高于中性条件下的降解速率．能促进OH等自由基形成的自由基促进剂Fe^2 和I^-等可有效加速亚甲基蓝的超声降解．

| Abstract: | This paper presented the research results of sonochemical decomposition of methylene blue in dilute aqueous solution.It was found that methylene blue can be decomposed with ultrasonic irradiation in aqueous solution.The sonochemical degradation kinetics of methylene blue in water is first order.The effects of initial concentratuioins,reaction temperature and pH of aqueous solution on the ultrasonic decomposition rate of methylene blue were studied and the influence of free radical accelerators such as Fe 2 and I - on the sonochemical degradation rate of methylene blue were also investigated. |
