摘要
本文对基本结构相似的三种偶氮染料橙黄Ⅱ、活性艳红X-3B和活性黑K-BR水溶液在铁粉还原-光氧化两步法处理中的紫外-可见光谱图作对比分析,依据其结构与特征吸收的关系,初步推测还原铁粉-光氧化法降解染料的历程.
We made comparison study on UV-Vis spectra of three azo dyes, Reactive Red 2, Orange Ⅱ and Reactive Black 8 in aqueous solutions during their treatment by iron metal reduction and pho-tooxidation. According to the relation between moleculestructures and absorption peaks of dyes, we proposed their reduction-photooxidation course.
