卷烟纸及烟丝钾钠比差异对卷烟主流烟气影响

Different Effects of Potassium-sodium Ratio Variation of Cigarette Paper and Cut-tobacco on Mainstream Smoke

为考察添加于不同主体柠檬酸盐助燃剂的钾钠比对卷烟主流烟气有害物质释放量影响的差异,利用电感耦合等离子体质谱仪(ICP-MS)对卷烟纸及烟丝中助燃剂钾钠盐实际含量进行测定,并研究比对卷烟纸及烟丝钾钠比对卷烟主流烟气的影响。结果发现,主流烟气烟碱量、焦油量及CO量均与卷烟纸钾钠比呈高度相关的幂函数关系,而与烟丝钾钠比相关性较弱。因此通过改变钾钠比对卷烟有害物质释放量进行调控时,应优先选择卷烟纸作为添加主体。

In order to investigate the effect of potassium-sodium ratio variation in different matrices on the release of harmful substances from mainstream cigarette smoke, the actual content of potassium and sodium in cigarette paper as well as cut-tobacco was determined by inductively coupled plasma mass spectrometry(ICP-MS). The variation of mainstream smoke caused by the change of potassium-sodium ratio of cigarette paper and cut-tobacco was studied respectively and systematically compared. Given the data fitting results, the content of nicotine, tar and CO of mainstream smoke had a power function relationship with the potassium-sodium ratio of cigarette paper, but had a weak correlation with the potassium-sodium ratio of cut-tobacco. Therefore, cigarette paper should be preferred as the substrate when the release of harmful substances from cigarettes was regulated by changing the ratio of potassium to sodium.
