| Abstract: | The effect of initial pH values on the degradation efficiency of the landfill leachates by catalytic wet air oxidation(CWAO) was studied and the relationship between pH value and the dissolution of the catalyst was investigated. Meanwhile, the kinetic process of the decomposition is described with Elovich equation, and the correction relationship is also described between initial pH value and the removal rate of the dissolution of the landfill leachates used. |
