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.
