摘要

美国商品卷烟的烟雾pH值因使用酸性和碱性卷烟添加剂而在4.2 ~ 8.2之间变化。在不同pH值的烟雾中,氢、氧、一氧化碳、二氧化碳、甲烷、乙烷、乙烯和氮氧化物的含量都有微小的减少或不显著的差异。在无过滤嘴香烟中,将pH值从5.6改变为8.2,蒸汽相中硫化氢的含量减少了79- 91%,氰化氢的含量减少了90%以上。使用活性炭-醋酸纤维素过滤器与碱性烟雾,进一步减少了这些成分。含有碱性或酸性添加剂的香烟的烟雾样本显示,甲醛、乙醛、丙烯醛、丙酮、乙腈和甲醇的含量略有减少,但其中一些成分的减少可能微不足道。

Composition Studies on Tobacco XXXVl: Changes in Smoke Composition and Filtration by Artificial Alteration of Smoke pH: Vapour Phase Constituents
Abstract The pH of smoke from U.S. commercial cigarettes was varied from 4.2 to 8.2 by the use of acidic and basic cigarette additives. Small reductions or insignificant differences were obtained in the levels of hydrogen, oxygen, carbon monoxide, carbon dioxide, methane, ethane, ethylene and oxides of nitrogen in smoke of varying pH. Reductions of 79-91 % of hydrogen sulfide and more than 90 % of hydrogen cyanide in the vapour phase were obtained by changing the pH from 5.6 to 8.2 in nonfilter cigarettes. Using an activated carbon-cellulose acetate filter with the alkaline smoke, further reductions were obtained for these components. Samples of smoke from cigarettes containing alkaline or acidic additive show some slight reduction in formaldehyde, acetaldehyde, acrolein, acetone, acetonitrile and methanol but the reductions for some of these components may be insignificant.
