超声／H2O2／CuO联合作用降解硝基苯

Decomposition of nitrobenzene using ultrasound/H_2O_2/CuO process

研究了在超声波/H2O2/金属氧化物体系中,金属氧化物(CuO,ZnO,Al2O3)对硝基苯降解的影响。结果表明:采用超声波/H2O2/CuO体系效果较好。对超声/H2O2/CuO联合作用的效果进行了研究,讨论了反应液的pH值、硝基苯的初始浓度等因素对硝基苯降解的影响。实验结果表明:pH值的变化对其降解效果没有明显影响;硝基苯的降解效果与其初始浓度有关,其降解过程符合一级反应动力学模型。

Nitrobenzene degradation was studied with various metal oxide （CuO/ZnO/Al2O3 ） in the ultrasound/ H2O2/metal oxides system. The results showed that the performance of the nitrobenzene degradation using the ultrasound/H2O2 ultrasound/ CuO was optimum among various metal oxides. With ultrasound/H2O2/CuO system, the factors such as pH, nitrobenzene initial density were discussed on nitrobenzene degradation. The results showed that the solution pH value had no obvious effect on nitrobenzene degradation; the nitrobenzene degradation was related to initial density, and the degradation process was fitted to be first-order reaction kinetics model.
