In order to investigate the ability of oxidative degradation of phenol by iron and manganese oxides, oxidative degradations of phenol by inartificial and synthetic iron and manganese oxides were discussed with the opposite experiments. Iron and manganese oxides in soil included inartificial goethite and manganese oxide, while synthetic iron and manganese oxides included synthetic goethite and pyrolusite. The results showed that phenol and iron and manganese oxides reacted with oxidation-reduction, while phenol and impurity in soil reacted with adsorption; the intensity of reduction reaction of iron and manganese oxides decreased rapidly with the increase of pH value of reaction medium; zero-order reaction kinetics equation was used to fit the reductive dissolution reaction of iron oxide, and the relationship between the intensity of reduction reaction of goethite and pH value of reaction medium was negative.
