1-Ethyl-3-methylimidazolium chloride (C 2 mimCl) ionic liquid molecularly imprinted polymer (C 2 mimClMIP/PS-DVB) was prepared on the surface of poly(styrene-divinylbenzene) (PS-DVB) by using C 2 mimCl as the template molecule, methacrylic acid (MAA) and ethyleneglycol dimethacrylate (EGDMA) as the bifunctional monomer. The preparation conditions were optimized and the molar ratio of 1∶4∶14 for C 2 mimCl∶MAA∶EGDMA was selected as the optimal polymerization molar ratio. Then infrared spectra (IR) spectrophotometer, scanning electron microscopy (SEM) and Brunauer-Emmett-Teller (BET) surface area and pore size analyzer were used to characterize the molecularly imprinted polymer, it was shown that C 2 mimClMIP/PS-DVB was successfully prepared on the surface of PS-DVB. The static adsorption experiments were performed in acetonitrile to investigate the adsorption properties and selective recognition characteristics of the polymer for C 2 mimCl and its structural analogues. Selective adsorption experiments showed that C 2 mimClMIP/PS-DVB has high selectivity for C 2 mimCl and C 4 mimCl. Adsorption isotherm experiments suggested that the maximum adsorption capacity of C 2 mimClMIP/PS-DVB and C 2 mimClNIP/PS-DVB for C 2 mimCl was 144.71 µmol/g and 22.56 µmol/g, respectively, and for C 4 mimCl was 124.53 µmol/g and 21.42 µmol/g. While the total number of binding sites N t , mean association constant K 0 and the heterogeneity index m of C 2 mimClMIP/PS-DVB were 130.9 µmol/g, 0.37 L/mmol and 0.8, respectively. C 2 mimClMIP/PS-DVB solid phase extraction column was prepared to investigate the solid phase extraction properties of C 2 mimClMIP/PS-DVB. Various parameters, such as the loading volume, flow rate and eluent solvent, were optimized for the C 2 mimClMIP/PS-DVB solid phase extraction column experiments. Then the dynamic adsorption experiments were carried out by coupling C 2 mimClMIP/PS-DVB solid phase extraction column with high performance liquid chromatography (HPLC), it was shown that C 2 mimClMIP/PS-DVB solid phase extraction column could separate and enrich
