微波协同活性炭氧化活性红X-3B中的H^+效应

The effect of H^+ on disposing the dyeing wastewater X-3B with microwave cooperated with activated carbon

通过考察不同pH值对微波协同活性炭氧化活性红X-3B处理效果的影响,探讨了H+的存在对反应进程的影响以及其相应的反应机理.试验结果表明:H+的存在的确能促进反应的进行,并能在一定程度上提高活性红X-3B的色度去除率以及TOC去除率,究其原因,H+的存在改变了废水溶液中活性红X-3B分子各型体的分布情况,并能使活性红X-3B以分子状态更易于被活性炭吸附.因此,H+的存在对于微波协同活性炭氧化活性红X-3B能起到事半功倍的效果.

The effect of the presence of H~ on the reaction process and the mechanism of the reaction were studied through analyzing how different pH values affect the treatment of dyeing wastewater X-3B by using microwave cooperated with activated carbon. The study showed that the presence of H＋ promoted the reaction and increased colority removal rate as well as TOC removal rate in some degree. It was deduced that H＋ changed the distribution of reactive dyes molecule X-3B and made the molecules be absorbed onto activated carbon easier. The results showed that the presence of H＋ promoted the disposal of the printing and dyeing wastewater using microwave cooperated with activated carbon.
