      Abstract A molecularly imprinted polymer (MIP) for the selective solid phase extraction of imidacloprid, imidaclothiz, thiacloprid was synthesized by polymerization for 24 h using thiacloprid as template. Dynamic adsorption and selective adsorption test showed that the MIP could quickly adsorb the imidacloprid, imidaclothiz, thiacloprid, with good selectivity for targets. The maximum static adsorption capacity of MIP was 31.7, 36.7 and 45.3 mg/g, respectively. A molecularly imprinted solid phase extraction (MIPSPE) was developed to separate, clean up and enrich the thiacloprid, imidacloprid and imidaclothiz residue in paddy water, soil, rice, tomato, cucumber. The average recoveries were 80.2%-98.8%, with relative standard deviation of 1.4%-4.5%. The MIPSPE was used to analyses the real samples, the result was satisfied.
