Preparation of Supported Fe/SiO_2 Catalyst and its Catalytic Performance for Wastewater Treatment

摘要

The catalyst Fe/SiO_2 was prepared by impregnation method and used as catalyst for treating the dye wastewater by catalytic wet peroxide oxidation method. The catalyst preparation process was optimized, and under the conditions of: the particle size of catalyst carrier was 0.125-0.200 mm, concentration of iron nitrate was 1.10mol/L, calcination temperature was 600°C, and calcination time was 4h, the catalyst has higher activity and better stability in treating the wastewater.
