Petrochemical manufacturing wastewaters often contain a high concentration of biodegradable com-pounds that possess either toxicity or activity inhibition to the biological unit. In this paper, COD removal from Petrochemical wastewaters by electro-Fenton process was studied. The effect of operating conditions such as reaction time, current density, pH, H2O2/Fe2+ molar ratio, and H2O2 of petroch...

For the treatment of 2-naphthol wastewater, homogeneous electro-Fenton process was considered as an effective method but some disadvantages greatly restrict its application. The three-dimensional (3D-EF) system using a nano zero-valent iron-supported biochar (NZVIs-BC) particle electrode and Cu-supported stainless steel (Cu-SSE) proposed to avoid electro-Fenton. In this work, 3D-EF developed, w...

In this study, Chemical Oxygen Demand (COD) removal efficiency from wood processing wastewaters by Fenton Process (FP) and Photo Electro (PEFP) were examined. Important operating parameters such as pH, Fe+2 concentration/(amper for PEFP), H2O2 concentration reaction time optimized. Optimum operation conditions of the FP pH 3.5, 1.4 gr/L Fe2+ 50 150 min. while they 3.00, 9.99 mA/cm2 current dens...

Pentadecafluorooctanoic acid (PFOA) is environmentally persistent, bioaccumulative, globally distributed and dangerous to human beings. Thus, the degradation of PFOA with effective method remains further exploration. Here, an Electro-Fenton (EF) system was studied for efficient PFOA degradation, and where a new composite material ferrous hierarchically porous carbon (FHPC) prepared by high temp...

The mineralization of tetracycline by electrochemical advanced oxidation processes (EAOPs) as well the study toxicity its intermediates and degradation products are presented. Electro-Fenton (EF), anodic (AO), electro-Fenton coupled with (EF/AO) were used to degrade on carbon felt (cathode) a sub-stoichiometric titanium oxide (Ti4O7) layer deposited Ti (anode). As compared EF AO, EF/AO system r...

A novel Pd-based electro-Fenton (E-Fenton) process has recently been developed to transform organic contaminants in groundwater. However, it only produces H2O2 and requires addition of Fe(2+). In this study, an innovative approach is developed to effectively regulate the generation of Fe(2+) from an iron cathode in a three-electrode system in addition to H2O2 production. The Fe(2+) is then used...
