不同抽吸条件对主流烟气中氰化氢分析结果的影响

Effect of the Different Smoking Indices on HCN in Cigarette Mainstream Smoke

[目的]研究不同抽吸条件对卷烟主流烟气中氰化氢分析结果的影响情况。[方法]采用流动分析法测定卷烟烟气中的氰化氢,分析了抽吸容量(30、35、40、45、50 ml)、抽吸间隔时间(30、60 s)2个抽吸参数与烟气中氰化氢的关系。[结果]缩短抽吸间隔时间,增加抽吸容量均可使烟气中氰化氢的量明显增加,相反,增加抽吸间隔时间,减少抽吸容量均可使烟气中氰化氢的量明显减少。[结论]人们吸烟时可以通过改变抽吸间隔和抽吸容量来降低烟气中的氰化氢,提高卷烟的吸食品质。

[Objective] The different smoking Indices affecting the testing result of the HCN in mainstream smoke of cigarette were experimented.[Method] The content of HCN in cigarette was tested with the continuous flowing analyzer.The correlation between HCN in cigarette mainstream smoke and two indices： the smoking amount（30,35,40,45 and 50 ml）and the smoking alternation（30 and 60 s）,was analyzed.[Result] The results indicated that the output of HCN in cigarette mainstream smoke was obviously increased as the smoking alternation was shortened and the smoking amount was increased.[Conclusion] The smoking alternation and volume could reduce the HCN absorbed by people.
