Description:
Advanced oxidation processes (AOPs) represent those technologies that bring about enhanced oxidative degradation of pollutants in aqueous solution by the generation of hydroxyl radical (•OH). US Environmental Protection Agency (EPA) published, in February 2005, the second Contaminant Candidate List (CCL), which specifies 51 unregulated priority contaminants for the Agency's drinking water program. Various pesticides are included in the CCL since their extensive use worldwide was found to have serious environmental consequences with major impacts on water quality (Chiron et al., 2000). The purpose of the study was to determine kinetic rate constants of the chemical reactions resulting from the application of UV and UV/H2O2 to the CCL pesticides: linuron (C9H10Cl2N2O2), diuron (C9H10Cl2N2O), prometon (C10H19Cl2N5O), terbacil (C9H13ClN2O2), diazinon (C12H21N2O2 PS), dyfonate (C10H15OPS2), terbufos (C9H21O2PS3), and disulfoton (C8H19O2PS3).
