Abstract
The present disclosure belongs to the technical field of analytical chemistry, in particular to synthesis and application of a nanomaterial for removal of patulin (Pat). The present disclosure adopts 2-Oxin as a substitute template, AM as a functional monomer, and synthetic Fe3O4@SiO2@CS-GO magnetic nanoparticles as a carrier, for preparing a magnetic MIP specific for Pat adsorption by surface imprinting. The addition of Fe3O4 makes the finally prepared molecular imprinted adsorbent material magnetic, thereby facilitating separation of a material from a matrix, eliminating complicated operation steps such as filtration and centrifugation, and facilitating recovery of materials.
