| 摘 要： | 以电化学循环伏安法研究了FeO42-、甲基橙、酸性铬蓝以及铬黑T等偶氮类染料的氧化还原电位.实验结果表明FeO42-有足够高的氧化电位来氧化偶氮类染料中的生色基团.用紫外-可见光谱法分析了FeO42-对甲基橙、酸性铬蓝、铬黑T等偶氮类染料的降解脱色行为.经高铁酸盐处理后偶氮染料类废水溶液中的有机成分逐渐减少,脱色率高于...

| Abstract: | I-V cyclic voltammogram,UV were used to discuss organic matter degradation.Results of I-V cyclic voltammograms showed the redox peaks corresponding to organic substance were not observed in the treated solutions.Instead,a couple of Fe3+/Fe2+ redox peaks were observed.IR results indicated that organic substance was decomposed.The degradation and the decolorization of dyes were confirmed by the measurements of visible spectrum and chemical analysis.The decolorization of azo dyes waste water was close to 100%,... |
