摘要
以 2 ,4 二硝基酚为研究对象 ,探讨了超声功率、氧化剂H2 O2 与Fenton试剂等因素对其超声降解效率的影响 .2 ,4 二硝基酚在超声波 (US)、US H2 O2 和US Fe2 + H2 O2 体系中的降解均符合一级反应动力学模式 .超声波和Fe2 + H2 O2 体系在 2 ,4 二硝基酚的降解过程中存在着协同效应 ,而在Cu2 + H2 O2 和超声波体系中未观察到相似的协同效应 .
The effects of ultrasonic power, addition of oxidant H_2O_2 and Fenton reagent on the degradation efficiency of 2,4-dinitrophenol by ultrasonic-wave treatment (US) were studied. The degradation of 2,4-dinitrophenol by US, US/H_2O_2 and US/Fe^(2+)/H_2O_2 respectively fitted first-order kinetics. It was found that the degradation of 2,4-Dinitrophenol by US can be enhanced by addition of Fe^(2+)/H_2O_2 mixture. However, the similar synergic effects were not observed for the degradation of 2,4-dinitrophenol when CuSO_4/H_2O_2 was added in ultrasound wave system.
