摘要

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.
