Abstract: Highly selective molecularly imprinted polymers (MIPs) that absorb sulfonamides (SAs) are prepared using two types of SAs as mixed templates, 2-vinylpyridine as the functional monomer and ethylene glycol dimethacrylate as the crosslinker. The optimum combination of the mixed templates, their adsorption effect and the imprinting mechanism are evaluated based on SPE recoveries of a family of analytes, equilibrium binding, BET surface area analysis and UV. The results indicate that the mixed templates not only optimize the cavities of the MIPs but also improve the MIPs selectivity and adsorption capacity for the target analytes in aqueous solution. Therefore, MIPs are used for the quantitative analysis of SAs in fish farming water using off-line SPE coupled to HPLC/DAD. The recovery and RSD were 84.16-101.19 and 1.98-7.10%, respectively. Four SAs analytes were detected in four types of water samples in the range of 8.49-74.60 ng L-1. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 41491
