Abstract
During the present research, the effect of some oxides ((TiO2, ZnO, Fe2O3)was studied as optical catalysts in light-photo-oxidation of some organic pollutants in water which are (phenol, chloroform, Alcrisol) and study the effect of some factors affecting the process of oxidation to remove contaminants such as the degree of heat, acidic solution, the concentration of contaminated material and the concentration of catalysts.The study was concluded by design system to remove the pollution-based payments batch mode)) .It proved its efficiency in removing 98% of the pollutants, which include a source of ultraviolet light gives wavelengths range (300 - 400 nm) and the capacity (125 W). From the obtained results ,it has been found that the efficience of optical catalysts with the presence of oxygen to remove contaminants follow the following order TiO2> ZnO> Fe2O3 The speed of retail optical oxidizing organic pollutants, they follow the order the following: CH3CI> Phenol> Cresol And finally "been diagnosed with some products of oxidation of pollutants.
