摘要(Abstract)：

以石墨碳毡(GF)为阳极,采用阳极氧化法对模拟染料废水——亚甲基蓝(MB)、结晶紫(CV)和罗丹明B(RhB)进行降解,分别考察外加电压、初始pH、染料初始质量浓度与电解质类型对染料降解效果的影响,采用扫描电子显微镜(SEM)和X线光电子能谱(XPS)对石墨碳毡的表面形貌与官能团进行分析。结果表明:石墨碳毡是由碳微丝交织而成的三维材料,存在含氧官能团和不饱和键,对有机染料具有较好的去除效果;常温常压下,外加电压为1.4V、初始pH为3,染料的初始质量浓度为25mg/L,电解质为Na2SO4时,染料的降解效果最优。石墨碳毡可以在较大的质量浓度范围与较宽泛的pH条件下阳极氧化降解染料,电压越高,染料的降解效果越好,但过高的电压将导致碳腐蚀。

关键词(KeyWords)：石墨碳毡;阳极氧化;染料去除;废水处理;不饱和官能团
