Abstract
A kind of catalyst Cu/Mn was prepared with the co-precipitation method, and applied to the treatment of pesticide wastewater from imidacloprid production by catalytic wet air oxidation. The influences of the roasting temperature and content of Cu/Mn on the activity and stability of the Cu/Mn catalyst were investigated, and the best preparation condition has been determined. The catalyst was characterized by means of BET specific surface area measurement and XRD. The experimental results indicated that the Cu/Mn catalyst was applied in the treatment of imidacloprid wastewater resulted in 93. 12% COD removal at Cu/ Mn catalyst. The Cu/Mn(Cu :/Mn = 2 : 1) was calcinated at 800 癈 and 16 hours . The concentration of leached Cu and Mn leaching is below 0. 3 mg/L. The preliminary theory calculation and analysis for the stability of the catalysts were made.关键词
