Abstract: The molecularly imprinted terpolymer was synthesized using pyrene as the template molecules by bulk polymerization. The adsorption ability and selectivity of the polymer were investigated by selectivity experiment. Scatchard analysis was employed to study the binding characteristics of molecularly imprinted polymer(MIP). Adsorption of polycyclic aromatic hydrocarbons(PAHs) was carried out to verify the interaction of MIP by solid phase extraction. The PAHs contents in the smoke of cigarette samples added with the MIPs to the filter were analyzed by GC/MS. The results show that the PYR-MIP is superior in terms of removing more than about 28% PAHs in the tobacco smoke. And the reduction rate of benzo[a]pyrene(B[a]P), benz(a)anthracene(B[a]A) and chrysene(CHR) are 31.08%, 25.69% and 27.33%, respectively, compared the commercial filter tip.
