Abstract: Synthesis, characterization and adsorption behavior of nicotine molecularly imprinted polymer (MIP) toward nicotine in solution and tobacco smoking was investigation in present work. Morphologic Structure and surface character of molecularly imprinted polymer was measured by thermo gravimetric analyzer (TGA) and scanning electron microscopy (SEM). Liquid chromatogram (LC) and gas chromatography-mass spectrometry (GC-MS) was used to qualitatively and quantitatively analyze the chemical composition changes before and after MIP adsorption, the adsorption thermodynamic and selectivity for this MIP was also investigated. The result showed that the MIP can selectivity adsorp nicotine with a selectivity coefficient of 2.275 for nicotine toward pyridine, a Δ H value of 3.516 kJ/mol indicated a endothermic adsorption process. The adsorption rate for nicotine by MIP, NIP and silica gel as adsorbent from tobacco smoking are 94.81%, 94.04% and 66.19%. It demonstrated the polymer had higher absorption capacity to the nicotine in tobacco smoking.
