摘　　要：随着有机染料在多个领域的大规模应用,染料废水污染已然成为水污染最主要的来源之一,然而其高效处理依旧存在一定困难。近年来,Electro-Fenton技术因其高效、绿色被广泛应用和研究。以罗丹明B(RhB)作为染料废水的典型污染物,利用Electro-Fenton技术对其进行降解特性研究,旨在探究其最佳反应条件。结果表明:阴极材料为碳纤维,阳极材料为Pt,C(RhB)=0.010 mmol·L^(-1),C(Na_(2)SO_(4))=70 mmol·L^(-1),C(Fe^(2+))=0.1 mmol·L^(-1),T=30℃,pH=3,E=10 V,该条件下体系氧化效能最高,能够实现RhB在5 min内完全降解。With the large-scale application of organic dyes in many fields,dye wastewater pollution has become one of the main sources of water pollution,but its efficient treatment still has some difficulties.In recent years,electro-Fenton technology has been widely applied and studied due to its high efficiency and green color.In this paper,rhodamine B(RhB)was taken as a typical pollutant of dye wastewater,and its degradation characteristics were studied with electro-Fenton technology,in order to explore its optimal reaction conditions.The results showed that,under the conditions of cathode material carbon fiber,anode material Pt,C(RhB)=0.010 mmol·L^(-1),C(Na_(2)SO_(4))=70 mmol·L^(-1),C(Fe^(2+))=0.1 mmol·L^(-1),T=30℃,pH=3,E=10 V,the system had the highest oxidation efficiency and achieved complete RhB degradation within 5 min.
