摘    要:以电化学I-V循环伏安法和紫外可见光谱分析(UV-Vis)研究了茜素红在电解槽中处理前后的电化学行为的变化,探讨了Fenton试剂的作用机制:电解生成的过氧化氢与阳极溶解的Fe^2 反应,生成羧基自由基(F enton试剂),进而对有机染料进行氧化反应,使其不饱和的-N=N-链断裂,分解成萘胺与氨基苯酚磺酸两个部分,从而达到使有机染料降解,脱色的结果,对工业染料废水处理的测试结果表明,在电解处理的头15min,脱色率和COD的去除率变化较大,电解处理1h后,COD的去除率约为70%,脱色率达100%。

关 键 词:染料废水  电化学降解  羟基自由基  电化学法  废水处理  Fenton试剂  脱色率

Abstract:An electro-chemical processing to produce Fenton reagent has been described. Fenton reagent having a high redox potential has been used as an oxidant in treatment of dye wastewater. Results of voltammometry method show that the redox peaks of dye are not found in the treated dye solutions instead of the O 2/H 2O 2 redox peak. The results of visible spectrum show that the absorbency decreased fast in the first half hour, the dye will co-deposit with the Fe-dye complex and Fe(OH) 3. The COD remove rate is about 70% and the decolorization rate is 100%.
Keywords:dye wastewater  degradation  Fenton reagent  electrochemistry
