The molecularly imprinted polymer (MIP) had been synthesized using ofloxacin as the template molecule and the modified ash microspheres as carrier by surface molecular imprinting technology. Binding properties and structure of MIP were investigated by ultraviolet spectroscopy and static method respectively. The results demonstrated that the synthesized MIP possess specific recognition selectivity and excellent binding affinity for ofloxacin. Compared with the surface imprinted material with silica gel as carrier, the prepared molecularly imprinted material had the characteristics of high adsorption capacity and favorable imprinted effect. The separation and enrichment effect of MIP as solid phase extraction (SPE) materials were better than that of C18. The SPE coupled with UPLC was used for analysis of ofloxacin in actual samples. The recoveries of the developed method were in the range from 82.0% to 96.7%, and the RSD was less than 5.5%. The results showed that the method could be used for the separation and enrichment of ofloxacin in chicken products.
