Degradation of Organic Pollutants in Water by Catalytic Ozonation

Different series of transition metal catalysts supported on Al₂O₃ were prepared by the impregnation method. The catalytic activity was measured in a batch reactor with ozone as the oxidizing reagent. The experimental results indicate that Cu/Al₂O₃ has a very effective catalytic activity during the ozonation of organic pollutants in water. The optimum conditions for preparing Cu/Al₂O₃ were systematically investigated with the orthogonal testing method. Furthermore, the results also show that the surface properties of catalyst are not compulsory for effective oxidation.
