中文摘要：

以具有高比表面积的活性炭纤维毡（ACF）为阴极,通过电芬顿反应降解艳红染料X3B,考察了X3B降解反应动力学和初始催化剂的离子形态对其降解效果的影响,并采用X射线光电子能谱（XPS）和紫外可见分光光度法（UV-Vis）测定了反应过程中电极表面和溶液中Fe2＋/Fe3＋的含量.结果表明：X3B降解符合一级动力学反应机理,初始催化剂离子形态对降解效果影响不显著,ACF表面和溶液中Fe2＋/Fe3＋的转化规律一致.

英文摘要：

Brilliant red X3B in dye wastewater was degradated by electro-Fenton method using high surface area activated carbon fiber（ACF） as a cathode.The effects of degradation reaction kinetics and ion form of the initial catalyst on its degradation were investigated.The content of Fe2＋/Fe3＋ on electrode surface and in the solution was characterized by X-ray photoelectron spectroscopy（XPS） and UV-Vis diffuse reflectance spectroscopy.The results showed that the degradation of X3B meets the first-order kinetics and there was little effect of the iron initial valence on its degradation.Moreover,the transformation performance of Fe2＋/Fe3＋ between the surface of ACF and the solution was consisteat with each other.
