An imidacloprid imprinted polymer was synthesized successfully by using crylicacid as functional monomers and ethylene glycoldimethacrylate as the cross-linker in methanol.The adsorption and selectivity of the polymer were studied.The polymer packed in SPE column was used to extract imidacloprid residue in garlic.The results indicated that two different kinds of recognition sites in the MIP and the MIP showed specific affinity toward imidacloprid.It′s likely to be a novel material for selective enrichment of the imidacloprid residue.
