Abstract: The invention relates to a method for preparing a magnetic magnesium oxide surface molecular imprinting solid phase extractant, which belongs to the technical field of environmental material preparation. The method comprises the following steps: preparing a magnetic magnesium oxide composite material by a coprecipitation method; then performing surface modification on the magnetic magnesium oxide composite material by cyclodextrin through a microemulsion method; finally preparing the surface molecular imprinting solid phase extractant based on the magnetic magnesium oxide composite material by suspension polymerization. A static state adsorption experiment is used for researching the adsorption balance, dynamics and selective recognition performance of the prepared imprinting adsorbent. The result shows that the magnetic magnesium oxide surface molecular imprinting solid phase extractant has high adsorption capacity, rapid absorption dynamic property and obvious thymol molecule recognition performance.
