Abstract

The invention relates to a method for degrading the acid orange 7 through a ferro-manganese bimetallic catalyst containing carbon and belongs to the technical field of water pollution treatment. The method for degrading the acid orange 7 comprises the specific steps that S1, the ferro-manganese bimetallic catalyst containing carbon is prepared; S2, a certain amount of acid orange 7 and peroxymonosulfate are evenly mixed to prepare a mixed solution; S3, the prepared ferro-manganese bimetallic catalyst containing carbon is added to the mixed solution in the second step, stirring is conducted, and the acid orange 7 is degraded through the ferro-manganese bimetallic catalyst containing carbon. According to the method, through the cooperation effect of iron and manganese in the ferro-manganesebimetallic catalyst containing carbon, respective reactions for circulation and catalysis of peroxymonosulfate are manually promoted, the efficiency of using the catalyst and an oxidant is high, and the effect of degrading the acid orange 7 is good. Meanwhile, the pH application range of the catalyst in the method is wide, the catalyst material has the magnetism, convenience is provided for circulation recycling of a magnetic separation method, and secondary pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of water pollution control, in particular to a method for degrading acid orange 7 with a carbon-containing iron-manganese bimetallic catalyst. Background technique [0002] Printing and dyeing wastewater is produced in the paint industry, textile industry and leather manufacturing industry, and with the improvement of synthesis technology, azo dyes characterized by azo bonds (N=N) are more and more widely used in the printing and dyeing industry. The wastewater produced has the characteristics of large volume, strong toxicity, carcinogenicity, mutagenicity and refractory degradation. Most of them contain aromatic functional groups and have complex structures. If these dye wastewaters are discharged directly without treatment, they will cause great harm to aquatic organisms and human health; therefore, the degradation technology of these wastewaters has attracted more and more attention. . Acid orange 7 is ...
