Abstract

The invention belongs to the technical field of inorganic material preparation, and particularly relates to a preparation method of a silicon-based heteropolyacid doped magnetic composite membrane material. The preparation method comprises the following steps: (1) adding a metal salt A, a metal salt B and graphene oxide into a solvent C, stirring, adding silicon-based heteropolyacid, and continuing to stir uniformly to obtain a mixed solution; (2) dissolving alkali in the mixed solution, and carrying out solvothermal reaction; and (3) carrying out suction filtration on a product prepared by the solvothermal reaction, and respectively washing and drying with ethanol and water to form a film. The preparation method of the silicon-based heteropolyacid doped magnetic composite membrane material is simple, the composition and the structure are controllable, the thickness of the membrane layer is controllable, the membrane layer has magnetism and is convenient to recycle and use, and the problem that the preparation process of the composite membrane material is complex is solved; the method is simple in process flow, environment-friendly, suitable for large-scale industrial production and wide in application prospect; the prepared silicon-based heteropolyacid doped magnetic composite membrane material is excellent in Fenton performance, recyclable and high in structural stability.
