Rice hull-based magnetic mesoporous silica adsorption material and solid-phase extraction column prepared from same

The invention discloses a rice hull-based magnetic mesoporous silica adsorption material and a solid-phase extraction column prepared from the same. A preparation method of the adsorption material comprises the following steps of: (1) preparing a rice hull ash solution; (2) preparing magnetic mesoporous silica; (3) dissolving a virtual template into a reaction solvent dimethyl sulfoxide, then sequentially adding a functional monomer, a cross-linking agent and the magnetic mesoporous silica prepared in the step (2), and performing ultrasonic mixing to obtain a prepolymerization solution; and (4) preparing a molecularly imprinted material, namely the adsorption material. According to the invention, an environment-friendly material prepared from a rice husk base is used as a carrier, a molecularly imprinted polymer is prepared by using a covalent and non-covalent hybridization method, a bifunctional monomer and a double-template means, the molecularly imprinted polymer is used for filling to obtain a solid-phase
