摘要
以电化学法制备的高铁酸盐对甲基橙、酸性铬蓝、铬黑T等偶氮类染料进行降解脱色.实验结果表明,经高铁酸盐处理后,偶氮染料红外谱图的主要谱峰消失,代之以CO32-的振动吸收峰;紫外光谱分析表明,染料的特征吸收峰逐渐减小直至消失.经对比,发现复合混凝剂FeO42-/Al(OH)4-比FeO42-对染料有更佳的降解脱色效果.
Azo dyes methyl orange,acidic eriochrome blue and chrome black T degraded by electro-generated ferrate was reported. The results showed after treated by ferrate, the main peaks of azo dyes' IR spectrums disappeared and new absorbtion peaks of CO_3^(2-) appeared, and UV-vis spectrums indicated specific peaks of azo dyes weakened gradually. The comparison of azo dyes degraded by FeO_4^(2-)/Al(OH)_4^- and FeO_4^(2-) showed the former has more powerful effectiveness.
