摘　　要：实验使用钛基二氧化铅电极为阳极,泡沫镍作阴极对模拟硝基苯废水,研究了不同因素对硝基苯去除率的影响。并通过单因素实验分析确定了最佳反应条件:硝基苯浓度为123mg/L,辅助电介质Na2SO4浓度为7.5g/L,FeSO4浓度为0.45g/L,电解电压为18V,电解时间为80min,极板间距为4cm。在此条件下去除率可达到90%。This experiment of degradation of nitrobenzene has been taken in the self-made device, using the Ti-SnO2 electrode as anode. The research mainly study on the influence of each factor upon the nitroben- zene removal rate and select the best operating conditions to deal with the wastewater with experiments on single factors. The best electrolysis conditions are as follows： the concentration of nitrobenzene was 123mg L-~ , the concentration of Na2SO4 was 7. 5g L-1, the concentration of FeSO4 was 0. 45g L-1, electrolysis voltage was 18V, electrolysis time was 80min, and the discharge gap is 4cm. Under this condition, the re- moval rate of nitrobenzene reached 90M.
