摘要
研究了光照下电生成Fenton试剂处理茜素红模拟废水.实验发现,光照可加快电生成Fenton试剂对茜素红的降解脱色速率.采用红外光谱、紫外-可见光谱、循环伏安等方法考察了光照对茜素红降解的机制,确定了光催化降解茜素红的反应机理,实现了光催化与电化学降解的联合应用.

Abstract:
A combined met hod that consisted of electrolysis plus illumination was carried out of the treat ment of alizarin red wastewater.The best removal efficiency was obtained with elect rochemical-illumination method. IR,UV-Vis,and cyclic voltammetry were used to investigate the action of illumination.The combination of electro-generated Fenton reagent and illumination has been proved to be highly effective for the treatment of alizarin red wastewater,and the mechanism of photocatalytic in system was discussed.
