In order to study how fiber chemical properties affect the adsorption of harmful compounds of thread embedded in cigarette filter.Boehm titration

FT-IR

cigarette smoke routine analysis

and amounts of harmful compounds released in cigarette mainstream smoke analysis were taken into consideration.Results showed that: 1) amounts of NH3 in mainstream smoke reduced with fiber acidity increasing;and HCN reduced with fiber total basic groups increasing;2) amounts of phenol in mainstream smoke was effected mainly by the quantities of lactone groups on fiber

and subsidiary effected by the acidity of fiber;3) amounts of crotonaldehyde reduced with amino groups of fiber increased.
