电芬顿法(electro-Fenton, EF)作为一种环境友好的高级氧化技术,具有反应条件温和,易控制等优点,能产生大量羟基自由基(·OH),且氧化能力强、矿化效率高,常常被应用于难降解污染物的深度处理。碳气凝胶(carbon aerogel, CA)是一种比表面积高,孔隙率丰富和导电性高,而且尺寸可调的新型碳基电极材料。在异相电芬顿...
Electro-Fenton (EF) with peroxi-coagulation (PC) as an emerging electro-chemical advanced oxidation method has been extensively applied to treat refractory wastewater. However, the studies on the pretreatment of the raw coke plant wastewater by EF process were still lacking. In this study, a lab...
图1EF处理有机污染物的过程 2.2影响因素 Electro-Fenton能产生无选择的强氧化性的 ● OH,可降解难处理 的污染物,包括农药污染物、染料溶液、药物和个人护理品(PPCPs) 和工业污染物,例如苯胺和酚类等。而不断优化Electro-Fenton的反 应条件,可增强其处理效果。其主要的影响因素包括:pH、阴极电极 材料、催化剂的...
On the one hand, Fe(III) can be slowly reduced by reacting with hydrogen peroxide in the EF chain reaction, suggesting that hydrogen peroxide has the ability to reduce Fe(III). If the capacity of Fe(III) to oxidize H2O2 is improved, the problem of poor Fe(III)/Fe(II) cycling in EF...

Removal of Rhodamine B (RhB) using graphite–graphite electro-Fenton (EF) system is investigated in the present study. The effect of various operational parameters on RhB removal was studied. Experimental results showed that RhB was removed completely by the reaction with generated from graphite ...
Polytetrafluoroethylene/ferromagnetic nanoparticle/carbon black (PTFE/MNP/CB)-modified graphite felt (GF) was successfully applied as cathode for the mineralization of rhodamine B (RhB) in electro-Fenton (EF) process. The modified cathode showed high decolorization efficiency for RhB solution even in ...
Electro-Fenton (EF), an advanced oxidation process, can be combined with a biological process for efficient treatment of wastewater containing refractory pollutants such as pharmaceuticals. In this study, a biological process was implemented in a sequencing batch reactor (SBR), which was either preced...
