ABSTRACT: Hydrogen cyanide (HCN) was
produced by flameless combustion of dried tobacco leaves for investigating the
adsorption on Na2CO3, NaHCO3 and proline (HNC4H7COOH). The
concentration of HCN could be produced steadily at 0.73 mg/dm3. For
the given 245 cm3 of smoke with the flow rate of 17.5 cm3/s, the efficiency of adsorption of HCN was improved to 80% by the addition of the optimal
amounts of Na2CO3, NaHCO3 and proline (HNC4H7COOH),
which were 10, 20, and 30 mg respectively. In the circumstances, the
breakthrough concentration was reduced to 0.15 - 0.20 mg/dm3.
