WebJan 1, 2024 · Photo-Fenton Processes The combination of hydrogen peroxide and UV radiation with a Fe 2+ or Fe 3+ ion produces more hydroxyl radicals and in turn, it … Abstract. The photo-Fenton system is an advanced oxidation technology for the oxidative degradation of recalcitrant organic contaminants in water, which is based on the photochemistry of iron complexes and the Fenton reaction. The efficiency of the photo-Fenton system in degrading water contaminants is … See more The Fenton reaction refers to the reaction of Fe(II) with H2O2 (Reaction 59.1). In general, •OH is known to be produced by the Fenton reaction as a reactive oxidant [9]. … See more Fe(III) exists in forms of complexes in water. In the absence of water constituents acting as ligands, Fe(III) basically forms hydroxo complexes. The speciation of … See more The photochemical reduction of Fe(III) into Fe(II) is the rate-determining step for the production of •OH (resulting in the oxidative degradation of organic … See more WebNov 16, 2024 · Photo-Fenton process is a commonly adopted advanced oxidation process. Advanced oxidation processes generate highly reactive hydroxyl radicals (OH·) which completely mineralise the organic contaminants. port ludlow washington lodging
