Aldehydes filtering effect of tips of lit cigarettes made of bamboo charcoal fibers

Cigarette filter tip is made from bamboo charcoal fibers.Then smoking is simulated and the content of aldehydes in the mainstream smoke is determined.Acetone is used to extract aldehydes in the total particulate matter adsorbed by the filter tip.Results suggest that bamboo charcoal fiber can significantly reduce the content of aldehydes and the total particulate matter in the mainstream smoke.With the increase of bamboo charcoal fiber mass ratio in the filter tip,the content of aldehydes gradually reduces,whereas the content of aldehydes in acetone leaching solution gradually increases.The content of aldehydes in the mainstream smoke in the tip of lit cigarette made of bamboo charcoal fibers is 51.82% lower than that made of acetate fibers.
