Surface molecularly imprinted polymer used for selectively absorbing sulfamonomethoxine and preparation method thereof and application thereof

The invention discloses a surface molecularly imprinted polymer used for selectively absorbing sulfamonomethoxine and a preparation method thereof and application thereof. The surface molecularly imprinted polymer used for selectively absorbing sulfamonomethoxine uses methanol as a solvent, vinyl silicone as a carrier, sulfamonomethoxine as template molecule, chloride1-allyl-3-vinyl imidazole ionic liquid as functional monomer, ethylene glycol dimethacrylate as a cross-linking agent, and azodiisobutyronitrile as an initiator, and the sulfamonomethoxine molecularly imprinted polymer adsorbent is prepared by chain initiation polymerization. The invention also discloses the preparation method of the surface molecularly imprinted polymer, and the application thereof in the pretreatment of the selective separation and enrichment of trace sulfamonomethoxine in the environment. The surface molecularly imprinted polymer adsorbent prepared by the invention has uniform particle size, strong preferential adsorption prop
