Abstract

The invention relates to a copper-based catalyst for degrading antibiotics and a preparation method of the copper-based catalyst. The preparation method of the copper-based catalyst comprises the following steps: (1) preparing an aqueous solution containing polyvinyl alcohol, copper salt and zinc salt to obtain a solution a, preparing an ethanol solution of gamma-glycidoxypropyltrimethoxysilane toobtain a solution b, and mixing the solution a with the solution b to obtain impregnation liquid; (2) mixing a carrier with the impregnation liquid, and carrying out aging and drying; (3) putting a material obtained in the step (2) into a tubular furnace for hydrothermal treatment; and (4) roasting the material obtained in the step (3) to obtain the copper-based catalyst. The preparation method disclosed by the invention is simple in process, easy to operate and relatively low in production cost; and the catalyst has the characteristics of high activity and good thermal stability, is particularly suitable for being used as a catalyst for degrading antibiotics, and can be widely applied to treatment of antibiotic wastewater.

Description

technical field [0001] The invention relates to the technical field of copper-based catalyst materials, in particular to a copper-based catalyst for degrading antibiotics and a preparation method thereof. Background technique [0002] Antibiotics began to be produced during the Second World War. As an important chemical agent, it played a very important role in the prevention and treatment of human diseases and animal and plant diseases. my country is the main producer of antibiotic agents. Although the output is constantly increasing increase, but due to many reasons such as technology, the utilization rate of raw materials is still low, and there are a large number of residual antibiotics in the discharged wastewater, which has caused serious pollution to the environment and not only affects the economic benefits of pharmaceutical companies. At the same time, it also had a serious impact on the social benefits of the enterprise. [0003] Treatment technologies for antibioti...
