The Adsorption Property of Nicotine-Imprinted Polymer

Liu Ying, Liu Xueliang, Wang Junde  (Dalian Institute of Chemical Physics, Chinese Academy of Sciences, Dalian 116012)  
Molecular imprinted polymer against nicotine was prepared and its binding affinity and selectivity to nicotine were evaluated by batch adsorption experiments. Nicotine-imprinted polymer exhibited higher affinity to nicotine compared to non-imprinted polymer; Scatchard analysis indicated that there were two classes of recognition sites in nicotine-imprinted polymer, which had different affinity to nicotine. Furthermore, compared to the adsorption behaviors of aminopyridines, nicotine-imprinted polymer displayed satisfying selectivity. The results in this study proved the possibility to selectively extract nicotine from tobacco smoke when the nicotine-imprinted polymer was used as solid-phase extraction material.
