6.2 6.2 Fenton and Fenton Processes
Fenton oxidation is a chemical reaction where iron reacts with H₂O₂, producing hydroxyl(•OH) radicals (Shemer et al., 2006). Widely used in AOPs due to their ease of use and effectiveness in breaking down a variety of ECs. Lucas and Peres (2015) achieved deterioration of four kinds of parabens by Fenton reagent: methylparaben, ethylparaben, propylparaben, and butylparaben. Solar Photoelectro-Fenton (SPEF) process degraded beta blockers such cendol, propranolol hydrochloride, and metoprolol tartrate with an efficiency of 88–93% (Klamerth and others, 2013).
