Abstract: Tobacco-specific nitrosamines are one of the most important groups of carcinogens in tobacco products. Using adsorbents as filter additives is an effective way to reduce tobacco-specific nitrosamines in cigarette smoke. Molecularly imprinted polymers (MIPs) using nicotinamide as template were grafted on the silica gel surface to obtain MIP@SiO2 and employed as filter additives to absorb tobacco-specific nitrosamines in mainstream cigarette smoke. Four milligrams of MIP@SiO2 per cigarette was added to the interface between filter and tobacco rod to prepare a binary filter system. The mainstream smoke was collected on an industry-standard Cambridge filter pad and extracted with ammonium acetate aqueous solution before analysis. Compared to the cigarette smoke of the control group, the levels of tobacco-specific nitrosamines with silica gel and with MIP@SiO2 were both reduced, and the adsorption rates of N-nitrosonornicotine, N-nitrosoanabasine, N-nitrosoanatabine, and 4-(methylnitrosamino)-1-(3-pyridine)-1-butanone with silica gel and with MIP@SiO2 were 20.76, 15.32, 18.79, and 18.01%, and 41.33, 34.04, 37.86, and 35.53%, respectively. Furthermore the content of total particle materials in cigarette smoke with silica gel was decreased evidently but showed no observable change with MIP@SiO2. It indicated MIP@SiO2 could selectively reduce tobacco-specific nitrosamines in the mainstream cigarette smoke with no change to the cigarette flavor
