    , Fenton, and photo Fenton under solar light is reported. The processes were carried out in a photochemical reactor with recirculation. Operating variables such as, pH, oil concentration and molar ratio of [H2O2]:[oil] were investigated to test their effects on the treatment efficiency of Fenton process.

    (photolysis) aided to decrease ∼65% of COD at neutral pH in a reaction time period of 15 h; whereas a decrease of 47% and ∼90% of COD was obtained by Fenton and photo Fenton treatment, respectively, after a reaction time of 50 min. It was observed a decrease in the decomposition of H2O2 in the solar photo Fenton process, in subsequent additions of H2O2, and H2O2+Fe2+.
