The invention discloses a method for carrying out arylboronic acid modification on the surface of an oxide containing hydroxy in the surface. The method comprises the following steps: adding an oxide material containing the hydroxy in the surface, 3-glycidyl ether propoxy trimethoxy silane, phenylboronic acid and triethylamine to an anhydrous alcohol solvent, wherein on the basis of the specific surface area of the oxide material containing the hydroxy in the surface, 1-8 microL of the 3-glycidyl ether propoxy trimethoxy silane and 0.5-10mg of the phenylboronic acid are added in the per square meter surface area, 5-100ml of the anhydrous ethyl alcohol is added to each gram of the material according to the mass of the oxide material containing the hydroxy in the surface, and the concentration of the triethylamine is 0.5-2% (v/v); carrying out stirring reaction at 60-90 DEG C for 4-24 hours, carrying out solid-liquid separation, and washing off residual reactants on the surface of solid. According to the method, the modifying quantity of the arylboronic acid can be improved; the technological process is shortened; the environment protection is facilitated; and the production cost can be reduced.
