2. EF-FeRe（ Electro-Fenton -Ferric Reduction）；该法原理与1基本相同，H2O2要依靠外加，不同之处在于Fenton反应直接在电解装置中进行。该法pH必须小于2.5。3. EF-FeOx (Electro-Fenton -Ferrous Oxidation)；该法又称牺牲阳极法。铁板为阳极，阳极电解将铁氧化成Fe2+，与加入的H2O2发生Fenton反应。4. EF H...
4. EF H2O2- FeRe (Electro-Fenton - H2O2- FeRe);其原理是H2O2和Fe2+均在阴极上现场生成,进而发生Fenton反应。 5. EF-H2O2 - FeOx(Electro-Fenton - H2O2- FeOx );在这种体系下H2O2在阴极产生,Fe+2 由牺牲阳极提供,进而发生Fenton反应。 6.EF-H2O2 (Electro-Fenton - H2O2);该方法又称阴极电Fenton法,...
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...

The right cathode material can bring great benefits to the EF process. Carbon-based materials are widely used in electric Fenton systems because of their elevated formation of H2 overpotential, reduced catalytic capacity for H2O2 disintegration, and favorable stability and conductance (Brillas et al....
In this work, a one-step solvent-thermal approach was used to synthesize an Mn-doped Fe 3 O 4 modified graphite felt (GF) composite electrode material (FeMn@GF), which was then used as the cathode in an Electro-Fenton (EF) system. The levofloxacin (LEV) in wastewater can be successful...
Fe3++e→Fe2+Electro-Fenton 有其自身的优势[1]: 电化学产生 H2O2, 可避免其在运输、 储存和操作的危险; 控制降解速率实现机理研究的可能性;(1)(2)(3)由于阴极持续的 Fe2+再生提高了有机污染物的降解速率, 这也减小了污泥; 在最佳条件下, 可实现低花费小的全部矿化的可行性。图 1 EF 处理有机污染物...
