Zearalenone functionalized graphene surface molecularly imprinted material, preparation method therefor and use thereof

A zearalenone functionalized graphene surface molecularly imprinted material, which has reduced graphene oxide (RGO) as a carrier, cyclododecyl 2,4-dihydroxybenzoate (CDHB) as a template molecule, 1-allylpiperazine (1-ALPP) as a functional monomer, trimethylolpropane triacrylate (TRIM) as a cross-linking agent, azodiisobutyronitrile (AIBN) as an initiator, and acetonitrile as a pore-forming agent;

• wherein the zearalenone functionalized graphene surface molecularly imprinted material is prepared by a preparation method comprising the following steps:
• adding CDHB, 1-ALPP, TRIM, AIBN and acetonitrile to a solvent in sequence to provide a first mixture, mixing the first mixture uniformly, injecting nitrogen to remove oxygen and sealing the first mixture, and subjecting the first mixture to ultraviolet light irradiation for 24 h or 60° C. water bath for constant-temperature reaction for 24 h to obtain a molecularly imprinted polymer, wherein the solvent is N,N-dimethylformamide (DMF);
• grinding the molecularly imprinted polymer, sieving it through a 100-200 mesh screen, and removing CDHB with an eluent to provide a product, drying the product at 40° C. overnight, to obtain a template-removed molecularly imprinted polymer;
• and
• dispersing graphene oxide (GO) into water or DMF, adding the template-removed molecularly imprinted polymer to provide a second mixture, subjecting the second mixture to ultrasound and mixing it uniformly, then adding hydrazine hydrate to provide a third mixture, heating the third mixture in a 90-95° C. water bath for 4-6 h, cooling the third mixture to room temperature, filtering the third mixture to obtain a powder, then washing the powder with water and ethanol in sequence for a plurality of times, and drying the powder at 60° C. for 1-2 h to obtain the zearalenone functionalized graphene surface molecularly imprinted material.
