Abstract: Cigarette filter tip is made from bamboo charcoal fiber. Then simulate smoking and determine the content of aldehydes in mainstream smoke. We use acetone to extract the content of aldehydes in the total particulate matter adsorbed by filter tip. Results suggest that bamboo charcoal fiber can significantly reduce the content of aldehydes and the total particulate matter in mainstream smoke. As of bamboo charcoal fiber ratio in the filter tips increasing, the content of aldehydes gradually reduces and the content of aldehydes in acetone leaching solution gradually increases. The content of aldehydes in mainstream smoke adsorbed by charcoal fiber filters is 51.82% lower than adsorbed by acetate fiber filters.

Key words: bamboo charcoal fiber, filter tip, mainstream smoke, aldehydes, total particulate matter
