Problems solved by technology

At the same time, in the actual research process of the inventors of the present application, it is also found that if the iron-manganese bimetallic organic framework is directly loaded on the reduced graphite oxide, the resulting composite material is still difficult to efficiently activate peroxodisulfate, so it is difficult to quickly and effectively The degradation of sulfamethazine in wastewater still has defects such as long reaction time and poor treatment effect, resulting in the iron-manganese bimetallic organic framework / reduced graphene oxide composite material still cannot be widely used to activate peroxodisulfate to achieve Effective Degradation of Sulfamethazine Wastewater

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a method for removing sulfamethazine by utilizing an iron-manganese bimetallic organic framework / modified reduced graphene oxide composite material. Background technique [0002] In the past century, a large number of antibiotics have been discovered, synthesized and used in clinical due to their excellent bacteriostatic and bactericidal effects. Among them, sulfamethazine (SMT) is a major sulfonamide antibiotic with functional Mission-SO 2 NH 2 -, commonly used to control infectious diseases and promote animal growth. About 90% of SMT is excreted into the environment in the form of animal feces because the drug cannot be completely absorbed by the animal's stomach. With the use of SMT, the SMT contained in the environment is increasing, which will cause the following hazards: poisoning aquatic organisms, interfering with human endocrine, increasing the ris...
