Background & Aims of the Study: Phenolic compounds have been extensively used in industries for applications such as petrochemical, oil refineries, papers, plastics, steel, pharmaceuticals, textiles, coal conversion, and so on. Specified amounts of Phenolic compounds are lost in the process of their manufacturing and utilization and often cause environmental pollution problems. So, removal these compounds of industrial wastewaters are necessary. The aim of this paper, is the photo-degradation environmental pollutant 2-Chlorophenol (2-CP) using photo-Fenton process which was used a photo reactor for photo-catalytic degradation of 2-CP in aqueous solution.

Materials & Methods: This is an experimental study on a laboratory scale. Fe2+ ions as a homogeneous catalyst applied for the degradation of 2-CP in aqueous solution. The study was performed on synthetic wastewaters that contain 2-CP pollutant. The effect of operational parameters such as: pH, initial concentration Fe2+, H2O2 concentration and temperature were studied. The effect of UV irradiation, UV/H2O2 and UV/Fe2+/H2O2 on photo-catalytic degradation of 2-CP were studied. The reaction kinetic was studied. In this paper, optimum conditions were determined for the photo-catalytic degradation of 2-CP using a factor at the time method.

Results: The optimal conditions for this reaction were obtained at pH of 6, initial concentration Fe2+ at 20 ppm, H2O2 concentration at 14 ppm and temperature at 45 °C. A first order reaction with rate constant (k=0.0375 min−1) was observed for the photo-catalytic degradation reaction. These experiments demonstrated that UV radiation, Fe2+ ions and H2O2 oxidation process were needed for the effective degradation of 2-CP.

Conclusion: The results showed that the photo-Fenton process can be suitable alternative to removal phenolic compounds from wastewaters.
