Study on catalytic wet oxidation of H-Acid Containing Water over Fe/SiO2 catalyst

摘要：

　　This study has investigated the degradation of H-acid (1-amino-8-naphthol-3,6-disulfonic acid) containing water by catalytic wet hydrogen peroxide oxidation method,in which the catalyst of Fe/SiO2 was prepared by impregnation technology.The effect of catalyst dosage,initial pH value,amount of hydrogen peroxide and reaction temperature on the degradation process have been discussed,and the results indicated that wet hydrogen peroxide oxidation is an effective method for treating the wastewater containing H-acid,under the conditions that:catalyst dosage was 2 g,initial pH value was 7,amount of hydrogen peroxide was 10 mL (0.83 time of theoretical required amount) and reaction temperature was 80 ℃,the COD and color removal rate can reach 87.3% and 96.5%,respectively.
