Abstract: A new method was developed for the determination of hydrogen cyanide in mainstream cigarette smoke by ion chro
matography with diluted sodium hydroxide as absorbent. No complicated sample pretreatment was required. The whole proce-
dure of determination could be completed in 10 min. Quantitative results were oblained by external standard method. The
method had good linearity with corelation coefficient of 0.9999 in the oncentration range from 2.50 10to 5.00 mg/L
Limit of detection based on signal-to-noise ratio of 3 was 5.3 x 10" mg/L. Recovery of hydrogen cyanide in mainstream
cigarette smoke ranged from 98.5% to 101. 2% with RSD of 2. 49%. Influence of cross-linked chitosan on hyrogen cyanide
in mainstream cigarette smoke was investigated. Results indicated that the content of hydrogen cyanide in mainstream cigare
smoke was significantly reduced, up to 45.6% at the peak
