Enhanced Electro-Fenton Mineralization of Acid Orange 7 Using a Carbon Nanotube Fiber-Based Cathode

Enhanced Electro-Fenton Mineralization of Acid Orange 7 Using a Carbon Nanotube Fiber-Based Cathode

A new cathodic material for electro-Fenton (EF) process was prepared based on a macroscopic fiber (CNTF) made of mm-long carbon nanotubes directly spun from the gas phase by floating catalyst CVD, on a carbon fiber (CF) substrate. CNTF@CF electrode is a highly graphitic material combining a high surface area (~260 m2/g) with high electrical conductivity and electrochemical stability. One kind o...

Mineralization of Ofloxcacin Antibiotic in Aqueous Medium by Electro-Fenton Process using a Carbon Felt Cathode: Influencing Factors

The aim of this work is to study the degradation and mineralization of antibiotic ofloxacin in aqueous medium using the Electro-Fenton method as advanced oxidation technology. In this context, Pt/carbon-felt cell was used to investigate the influence of various parameters including initial pH, different supporting electrolytes, different metal ions as a catalyst and antibiotic concentration ove...

Pharmaceutical Wastewater Chemical Oxygen Demand Reduction: Electro-Fenton, UV-enhanced Electro-Fenton and Activated Sludge

In this study, Chemical Oxygen Demand (COD) from a pharmaceutical wastewater (PhW) was reduced by several techniques such as electro-Fenton (EF), photo electro-Fenton (PEF) and activated sludge (AS) processes and the obtained data were compared with each other. The effects of several parameters such as pH, current density, H2O2/Fe2+ molar ratio, volume ratio of ...

Degradation of Azo Dye Reactive Black 5 and Acid Orange 7 by Fenton-Like Mechanism

Fe2V4O13 assisted hetero-Fenton mineralization of methyl orange under UV-A light irradiation

Fe2V4O13 is prepared and characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR), UV-diffuse reflectance spectroscopy (UV-DRS), high resolution scanning electron microscopy (HR-SEM) using energy dispersive X-ray spectroscopy (EDX) analysis. The hetero-Fenton catalyst can be used to mineralize Methyl Orange (MO) under UV-A light. The mineralization rate is influenced by hydr...
