Modeling of Electro-Fenton Process

2017
From the conventional Fenton process (H2O2 and Fe2+), the electro-Fenton process was derived to improve the hydroxylation method (partial organic oxidation). Thereafter, electro-Fenton was adapted to water remediation. Since then, this approach has received much attention for wastewater treatment because it is an eco-friendly process and its ...

Radical and non-radical cooperative degradation in metal-free electro-Fenton based on nitrogen self-doped biochar.

Journal of Hazardous Materials, 2022
To achieve sustainable metal-free electron-Fenton, N self-doped biochar air-cathode (BCAC) was prepared by pyrolyzing coffee residues. During the pyrolysis process, the endogenous N transformed from edge-doping to graphite-doping.

Destruction of nitrotoluenes in wastewater by Electro-Fenton oxidation

Journal of Hazardous Materials, 2009
Electrolytic degradation of dinitrotoluenes (DNTs) and 2,4,6-trinitrotoluene (TNT) in wastewater was conducted by Electro-Fenton's reagents. The batch-wise experiments were carried out to elucidate the influence of various operating variables on the electrolytic behavior, including electrode potential, oxygen dosage, electrolytic temperature, acidity ...

Efficient electro-Fenton degradation of organic pollutants via the synergistic effect of 1O2 and •OH generated on single FeN4 sites.

Science of the Total Environment
The electro-Fenton with in situ generated 1O2 and •OH is a promising method for the degradation of micropollutants. However, its application is hindered by the lack of catalysts that can efficiently generate 1O2 and •OH from electrochemical oxygen ...

A new strategy for improving the energy efficiency of electro-Fenton: Using N-doped activated carbon cathode with strong Fe(III) adsorption capacity to promote Fe(II) regeneration.

Journal of Environmental Management
Fe(II) regeneration plays a crucial role in the electro-Fenton process, significantly influencing the rate of ·OH formation. In this study, a method is proposed to improve Fe(II) regeneration through N-doping aimed at enhancing the adsorption capacity of

Degradation of diuron by the electro-Fenton process

Environmental Chemistry Letters, 2003
The degradation of the herbicide diuron has been undertaken by electrochemical advanced oxidation in aqueous solution. This process generates catalytically hydroxyl radicals that are strong oxidizing reagents for the oxidation of organic substances. Hydroxyl radicals degrade diuron in less than 10 min.
