摘　　要：应用photo-Fenton过氧化过程研究对硝基苯水溶液的降解。测定反应物质量质量浓度、温度和pH对硝基苯降解的影响。使photo-Fenton法更加有效的降解水溶液中的硝基苯。在pH等于3、初始质量质量浓度H2O2为200 mg/L、Fe2+为30 mg/L条件下仅在30min内应用photo-Fenton法可将硝基苯降解50%左右(硝基苯初始质量浓度为200 mg/L)完全降解。Advanced oxidation processes （AOPs） using photo-Fenton treatment was investigated at laboratory scale for the degradation of aqueous solutions of nitrobenzene. The effects of reactants concentration, temperature and pH on nitrobenzene degradation were measured. Photo-Fenton treatment can successfully degrade the nitrobenzene in the aqueous solution. At pH be equal to3,and with initial concentrations of 200 mg/L for H202 and 30 mg/L for Fe（II）,the photo-Fenton treatment degraded the nitrobenzene of 50% （initial NB concentration of200mgL ） in only 30 rain.
