The invention discloses a method for degrading antibiotics with ionic liquid water phase transfer catalyzed by hydrogen peroxide. Hydrogen peroxide is added to wastewater containing antibiotics, and the pH of the system is adjusted to 3-4 to form a water phase; Add a catalyst and stir to form an ionic liquid phase, the catalyst is ferrocene, iron dodecyl sulfonate, ferrous dodecyl sulfonate or copper dodecyl sulfonate; water phase and ionic liquid phase by volume The ratio of 8~11:1 is mixed and stirred to react to degrade antibiotics. The method of the invention has the advantages of simple process, high reaction efficiency, low requirements for reaction conditions, complete degradation, no secondary pollution, energy saving and environmental protection, and a wide range of treatable antibiotics. The ionic liquid and the catalyst can be used repeatedly, so that the cost is significantly reduced. The inventive method has broad application prospects. |
