中文摘要：

文章采用傅里叶变换红外光谱（FTIR）结合气溶胶流管技术（AFT）和衰减全反射技术（ATR）分别得到香烟整体烟气和气溶胶的红外谱图。通过解析红外谱图可得到丰富的基团振动信息,1230cm-1处为酚类化合物的C—O伸缩振动峰,1735cm-1处的尖峰为羧酸中羰基的伸缩振动峰。由于烟气中气体占主要比例,所以CO在2118和2170cm-1出现较强的双峰,2343和2362cm-1为CO2特征吸收峰,其强度远远高于其他峰的强度。而气溶胶谱图中最明显的不同就是CO峰消失,CO2峰强度也大大减弱。因此将两种技术结合,特别是通过分析对比某些特征峰的变化,得到香烟烟气所发生的化学变化、组分挥发以及形态聚集等动态变化过程。为分析香烟燃烧产物提供了一个新思路,且不需对样品进行预处理,具有方便、快捷、无损等优点。

英文摘要：

In the present paper, Fourier transform infrared aerosol flow tube （FTIR/AFT） and Fourier transform infrared attenuated total refleetion （FTIR/ATR） were used as eredible teehnologies to study the eigarette mainstream smoke and eigarette aerosol. In the experiment a eonvenient and effeetive setup was used to deteet the sample. Before the eigarette was fired, the filter tip should be eut. Then the eigarette was eonneeted with the sample ehamber by a gluey tube. The mainstream eigarette smoke was imported by a vaeuum pump. The teehnology of FTIR/AFT eould get the information of the whole eigarette smoke including the ehief gas phase and fine solid partieles. A main peak at 1230 cm-1 , eontributed by the C--O stretching band, indieated the existenee of hydroxybenzene. A aeuate peak at 1 735 cm-1 was eontributed by the C=O stretehing band of earboxyl aeide. In addition, the strong peak of CO and CO2 gas ean be resolved. Two relative strong peaks at 2 118 and 2 170 cm-1 , respeetively were eontributed by CO gas. As to the gas CO2, two strong peaks were observed at 2 343 and 2 362 cm-1 , respeetively. While by taking the advantage of FTIR/ATR, we eould obtain the information of eigarette aerosols deposit on the ZnSe substrate. The speetra of aerosol was eorrespondingly simple. The peak of CO disappeared and the peak intensity of CO2 deereased greatly. Therefore, using the AFT and ATR teehniques eould help to understand the formation and the eomposition of the produetion of the burning eigarette more elearly. Espeeially, by analyzing the ehange of some eharaeteristie bands with time, the proeesses of the ehemieal reaetion, volatility of some eomponents and theform eonglomeration of eigarette eombustion were investigated. This has offered a new viewpoint in eigarette study that is different from eonventional ideas, and is simple and rapid without pretreatment.
