Photo fenton oxidation
WebJul 8, 2024 · The homogeneous Fenton method as an advanced oxidation process (AOP) is a widely used advanced oxidation process which has proven to be effective for the degradation of most of non-biodegradable organic pollutants [ 27, 28 ]. WebJun 10, 2024 · After coagulation, solar photo-Fenton oxidation removed up to 94% of COD. In this process, Fe 2+ should be chosen to promote the regeneration of Fe(II). Otherwise, at higher Fe(II) concentration, the penetration efficiency of light decreases. At lower Fe(II) concentration, ...

WebJul 5, 2024 · The intensive production of fossil fuels has led to serious polycyclic aromatic hydrocarbon (PAH) contamination in water and soil environments (as PAHs are typical types of emerging contaminants). Bio-Fenton, an alternative to Fenton oxidation, which generates hydrogen peroxide at a nearly neutral pH condition, could ideally work as a pretreatment … WebNov 12, 2024 · A photo-Fenton process operated under UVC light irradiation, at spontaneous pH, with 1.0 g/L of catalyst and 30 mg/L of H 2 O 2 was the most effective process, resulting in 98% CV dye removal within 3 h. LC-MS and ion-chromatography techniques were used to identify demethylated organic intermediates during the process.
Webefficiency of the Fenton and photo-Fenton reactions increases from 65 to 90% as the concentration of hydroxyl radicals (•OH) increases. No significant difference in the ammoniac nitrogen amount reduction for the Fenton and Photo-Fenton processes was observed, either before or after coagulation.
