Carbon felt (CF) is frequently used as an electrode in various processes of oxygen reduction reactions (ORR) and water treatment. Therefore, it critical to increasing the performance this material ORR. In study, effect thermal modification, which a simple low-cost process, was examined. For testing hydrogen peroxide generation efficiencies mineralisation Acid Orange 7 (AO7) dye, modified CF ele...

INTRODUCTION Human serum albumin (HSA) is a critical protein in human blood plasma, which can be highly damaged by oxidative stress. The aim of this study was to analyze modifications of this protein after oxidation using a Fenton system. METHODS In this 2015 experiment, different ratios of Fenton reagent (Fe2+/H2O2) was incubated with one concentration of human serum albumin (1mg/ml). Hence,...

Electrochemically induced Fenton (electro-Fenton) reaction was used for efficient and controllable preparation of hydroxyl radicals, leading to the generation of luminescent quantum dots through etching of as-exfoliated MoS2 nanosheets. Morphologic changes of MoS2 nanosheets during the electro-Fenton reaction were monitored using transmission electron microscopy, showing that etching of MoS2 na...

Electro-Fenton reactions can be very effective for organic pollutant degradation, but they typically require non-sustainable electrical power to produce hydrogen peroxide. Two-chamber microbial fuel cells (MFCs) have been proposed for pollutant treatment using Fenton-based reactions, but these types of MFCs have low power densities and require expensive membranes. Here, more efficient dual reac...

It has long been recognized that the aqueous mixture of hydrogen peroxide and ferrous ion, known as the Fenton reagent, generates powerful oxidants. Furthermore, the chemical intermediates and reaction pathways of the type generated by this reagent have been implicated in oxidative damage in biological systems. Although the subject continues to be debated, the hydroxyl radical (.OH) is generall...

Degradation products formed during removal of an aqueous nonylphenol ethoxylate compound (NP-10) by the H2O2/UV-C, Fenton (Fe/H2O2) and photo-Fenton (Fe/H2O2/UV) advanced oxidation processes and their relationship with the acute toxicity toward Vibrio fischeri photobacteria were investigated. Polyethylene glycols with 3-8 ethoxy units, aldehydes and carboxylic acids were identified as the prima...

Ethylenediaminetetraacetic acid (EDTA) is a chelating agent that has been used for decontamination purposes in nuclear industry. The presence of EDTA in decontamination wastes can cause complexation of the cations resulting into interferences in their removal by various treatment processes such as chemical precipitation, ion exchange etc. Further, it might also impart elevated leachability of c...

Sickle erythrocyte (RBC) membranes were previously shown to manifest increased Fenton activity (iron-dependent, peroxide-driven formation of hydroxyl radical [.OH]) compared with normal RBC membranes, but the nature of the catalytic iron was not defined. We now find that sickle membranes exposed to superoxide (.O2-) and hydrogen peroxide (H2O2) have three distinct iron compartments able to act ...

This study presents a machine learning (ML)/artificial intelligence (AI)-based perspective to reliably predict and enhance the treatment efficiency of landfill leachate by classical-Fenton (c-Fenton) photo-Fenton (p-Fenton) processes. experiment also sought lower costs evaluating impact using different numbers UV-c (254 nm) lamps during p-Fenton processes, as well develop sustainable process de...
