| 英文摘要 | a sorbent showing specific affinity for nicotine was prepared by molecular imprinting technique, using nicotine as the template, methacrylic acid (maa) as the functional monomer, ethyleneglycol dimethacrylate (edma) as the crosslinker and chloroform as the porogen. uv spectroscopic analysis in the molecular imprinting prepolymerization stage confirmed that nicotine could complex with the functional monomer by electrostatic interaction (ionic interaction and hydrogen bonding). the affinity and the binding properties of the imprinted polymer towards nicotine were investigated by equilibrium rebinding experiments. the results indicated the presence of nicotine-specific binding sites in the imprinted polymer, and that the imprinted polymer had a good capacity (90 mumol/g polymer) for nicotine. the elution conditions were optimized on the column packed with the imprinted polymer to elute nicotine quantitatively. the imprinted polymer was used as a solid-phase extraction (spe) material for the removal of nicotine from tobacco smoke. the results obtained showed that the imprinted polymer was superior in terms of removing nicotine in tobacco smoke, compared with the commercial filter tip. |
