碳毡电极电芬顿降解甲基橙研究

Degradation of methyl orange dye wastewater by electro-Fenton with carbon felt electrode

研究了碳毡电极电芬顿对偶氮类染料废水甲基橙的降解,并研究了pH、电流、氧气流量等实验条件对废水降解的影响。结果表明,在pH=3、电流为25 mA、氧流量为100 mL/min条件下,初始浓度为100 mg/L的甲基橙的脱色率达95%左右;与脱色相比,染料矿化需要更长的处理时间,处理180 min,矿化率达到40%左右。

The degradation of methyl orange in azo dye wastewater by carbon felt electrode electrochemical Fenton was studied,and the effects of pH,current,oxygen flow and other experimental conditions on the degradation of wastewater were studied.The results showed that the decolorization rate of methyl orange with initial concentration of 100 mg/L was about 95%under the conditions of pH=3,current of 25 mA and oxygen flow of 100 mL/min.Compared with decolorization,dye mineralization requires a longer processing time,180 min,the mineralization rate reached about 40%.
