Comparison of Fenton and electro-Fenton processes for oxidation of phenol

Synthesis of Cu2O–CuFe2O4 microparticles from Fenton sludge and its application in the Fenton process: the key role of Cu2O in the catalytic degradation of phenol

“…The present work focus on the synthesis of a heterogeneous Fenton catalyst, namely Cu 2 O-CuFe 2 O 4 , for the reuse of iron incorporated in Fenton sludge. In comparison to CuFe 2 O 4 , much higher phenol catalytic degradation was found for Cu 2…”

“…Fenton oxidation technology, which is well known as advanced oxidation processes (AOPs), has been extensively used to remove various recalcitrant or non-biodegradable organic pollutants from industrial wastewater. 1,2 During Fenton process, a powerful oxidant, hydroxyl radicals (HOc) can be generated efficiently at near-ambient temperature and pressure by the reaction between Fe 2+ and H 2 O 2 . 3 The distinct properties of generated hydroxyl radicals (HOc) such as strong oxidation potential (E 0 ¼ 2.8 V) and non-selective reactivity are considered to be responsible for the effectiveness of AOPs in the eld of organic pollutant elimination.…”

Electro-Fenton for Industrial Wastewater Treatment: A Review

“…[16] also conducted an experiment to exclude antimicrobial sulfamethazine, carried out experiments on acidic pH conditions to neutral (2 -6) and obtained optimal pH 3. Other studies confirmed that the electro-Fenton process is optimal in acidic conditions indicated [19] which removes phenol by comparing the Fenton process and electro-Fenton.…”

Efficient Fe/CuFeO2/rGO nanocomposite catalyst for electro‐Fenton degradation of organic pollutant: Preparation, characterization and optimization

“…This can be related to the inadequacy of ● OH for degradation of catechol. In high concentrations, more ● OH for complete removal of catechol and its degradation intermediates is needed …”
