Abstract: The invention relates to a magnetic adsorbent and a preparation method and application thereof. Fe3O4 microspheres with a particle size of 400nm are synthesized by using a solvent thermal reduction method and are used as a matrix, a layer of SiO2 is wrapped on the surface of the matrix first, then, a silane coupling agent AAAPTS is grafted, and finally, a functional function group succinic anhydride is grafted, so as to prepare the magnetic adsorbent Fe3O4-SiO2-AAAPTS-Di that is used for enriching and separating Th in a water solution. The magnetic adsorbent prepared by the method can be usedas a precursor of an ion imprinted polymer due to the selectivity, thereby having a bright application prospect. The corresponding ion imprinted polymer can be synthesized by using a certain chemicalmethod, so as to selectively separate the target ion Th in water phase easily, quickly and efficiently.
