Composition for oxytetracycline catalytic degradation and preparation method thereof

The invention relates to the technical field of catalytic oxidation, in particular to a composition for catalytic degradation of oxytetracycline and a preparation method of the composition. The composition for catalytic degradation of oxytetracycline is prepared from the following raw materials in parts by weight: 5-15 parts of chemically modified biochar, 15-45 parts of ferrite, 10-30 parts of metal sulfide, 5-15 parts of natural polymer colloid, 4-8 parts of tin-based metal carbide or titanium-based metal carbide and 1-2 parts of polyethyleneimine. According to the composition for oxytetracycline catalytic degradation, biochar is acetylated, so that the biochar is loaded with more active functional groups, and the OTC oxidative degradation capacity of H2O2 is improved. According to the composition for oxytetracycline catalytic degradation, the biochar is loaded with tin-based and titanium-based metal objects at the same time, the H2O2 oxidative degradation capacity during low-concentration OTC can be remark
