Abstract Fenton processes allow to degrade and mineralize toxic organic contaminants, yet classical require continuously adding hydrogen peroxide ferrous ions, costly solution pH adjustment, treatment of secondary iron sludge pollution. Heterogeneous electro-Fenton deliver oxidizing radicals with only oxygen electricity consumed. Bifunctional catalysts the synthesis activation simultaneously, e...

The feasibility of an electro-Fenton process to treat tylosin (TYL), a non-biodegradable antibiotic, was examined in a discontinuous electrochemical cell with divided cathodic and anodic compartments. Only 15 min electrolysis was needed for total tylosin degradation using a carbon felt cathode and a platinum anode; while 6 h electrolysis was needed to achieve high oxidation and mineralization y...

The present work reports the development and application of gas diffusion electrode (GDE) based on carbon Printex L6 modified with 5% Co-Porphyrin/CPL6 for removal Bisphenol S (BPS) in wastewater using different electrochemical advanced oxidation processes (EAOPs). GDE led to in-situ generation 333 mg L?1 H2O2 only 90 min; this represents an increase 88% relation unmodified GDE. process involvi...

A recently developed Pd-based electro-Fenton (E-Fenton) process enables efficient in situ remediation of organic contaminants in groundwater. In the process, H₂O₂, Fe(II), and acidic conditions (~pH 3) are produced in situ to facilitate the decontamination, but the role of ubiquitous natural organic matters (NOM) remain unclear. This study investigated the effect of Aldrich humic acid (HA) on t...

Advanced oxidation processes (AOPs) have been reported as alternative ways for treating reverse osmosis (RO) concentrate which is the primary concern water reclamation plants. AOPs are known to oxidize recalcitrant organic compounds by a highly reactive and nonselective oxidant, hydroxyl radical (<sup>?</sup>OH). Researchers showed that such conventional Fenton, UV/H<sub>2<...

Abstract In this study, the Fenton/adsorption of dye effluent containing Levafix blue has been carried out via a cost-efficient and eco-friendly heterogeneous Fenton solar-Fenton methods. Alum sludge, water treatment by-product were successfully collected calcined to 400 °C (AS400) tested for use as catalyst in process. X-ray diffraction, Scanned electron microscopy techniques applied investiga...
