The invention discloses a method for removing tetracycline hydrochloride in water by catalytically activating sodium persulfate under visible light by using a CeO2 composite BiOI material. The methodcomprises the following steps: preparing a rare earth oxide CeO2 composite BiOI material; adding a certain amount of rare earth oxide CeO2 composite BiOI material into a tetracycline hydrochloride aqueous solution, uniformly mixing, and carrying out ultrasonic treatment at room temperature at the frequency of 20khz for 20-45min so that the nano powder of the rare earth oxide composite BiOI material is uniformly dispersed into the tetracycline hydrochloride aqueous solution; adding a certain mass of sodium persulfate into the mixed solution of the rare earth oxide CeO2 composite BiOI material and tetracycline hydrochloride, quickly and uniformly stirring with a glass rod, and carrying out a catalytic reaction under visible light illumination; the method is high in removal rate, short in removal time and simple in process operation, and degradation byproducts are non-toxic and harmless; meanwhile, the selected rare earth oxide is small in dosage, low in price and controllable in cost.
