Assessment the efficiency of Fenton process (Fe 2+ /H2O2), versus photo-Fenton reaction (TiO2/Fe 2+ /H2O2/UV) for removal of Chloropyrifos, and COD from pesticide wastewater were investigated. Solar compound parabolic collectors (CPC) pilot scale with borosilicate tubes was used for photo-Fenton process. The effect of reaction time, initial pH and dosage of H2O2, FeSO4, TiO2 were studied for bo...
