This study was conducted to evaluate the effect of triacetin(TA) treatment during manufacturing carbon dual filter for the adsorption of cigarette smoke components by activated carbons. The measurements were carried out by separation of activated carbon from carbon dual filter, and the specific surface area analyzed. The specific surface area of activated carbon from the domestic cigarette filter and from the foreign cigarette filter by degassing at 9$0^{\circ}C$ was 163$\pm$32$m^2$/g, and 16.6$\pm$1.9$m^2$/g, respectively. Those values were very lower than that of degassing at 35$0^{\circ}C$ (Domestic brand: 952$\pm$30$m^2$/g, and Foreign brand: 847$\pm$73$m^2$/g). By comparing the adsorption capacity of acetone and benzene with and without triacetin treated activated carbon, there was a 20% reduction of adsorption capacity by 5% triacetin treatment. Also, from the cilia toxicity test with carbon dual filter treated 0 % TA and 8 % TA, the cilia survival time was 706$\pm$74sec. and 603$\pm$64sec. for 0% TA and 8% TA, respectively. The delivery rate of vapour phase of cigarette smoke, which consists of main components of cilia toxicity, was higher at 8% TA filter than 0 % TA filter. Our results indicate that the treated TA covered the micro-pore of activated carbon, and then reduced specific surface area, finally, decreased the adsorption of vapour phase from cigarette smoke.
