A magnetic polymer adsorption material, preparation method and use thereof, which relate to the field of magnetic polymer materials. The preparation method comprises: (1) preparing magnetic nanoparticles; (2) dissolving the magnetic nanoparticles in a pore-forming agent, adding N-vinylpyrrolidone, divinylbenzene and an initiator respectively, and mixing uniformly; (3) adding an emulsifier and a dispersant into an aqueous solution; adding a part of the oil phase solution prepared in step (2) at the temperature below 60&#xb0; C., and adding the rest of the oil phase solution when the temperature rises to 60&#xb0; C. or above, reacting with stirring, precipitating and filtering the reacted solution, washing and drying the precipitate, and finally obtaining the magnetic polymer adsorption material. The material has the particle size of 2-100 &#x3bc;m, the magnetization of 5-19.5 emu/g and the specific surface area of 210-950 m/g, and can be applied to the adsorption of inorganic and organic matters in solutions, the controlled release of inorganic and organic matters, and the separation of different substances.
