摘要
卷烟主流烟气粒相物经二氯甲烷浸提,进行GC/MS分析,对通风、加长滤嘴后卷烟主流烟气粒相物中21种挥发性、半挥发性酸性成分的变化进行了分析研究。结果表明:通风度20%卷烟2、5 mm滤嘴卷烟与参比卷烟(20 mm滤嘴、不打孔)相比,21种酸性成分总量分别减少了22.1%、26.3%。通风、加长滤嘴后卷烟主流烟气粒相物中不同酸性成分减少的程度不同,分子量较小、沸点较低的物质减少较多,而分子量较大、沸点较高的物质减少较少。
Effects of ventilation dilution and filter elongation on twenty-one volatile and semi-volatile acidic components in mainstream smoke particulate matters were studied through analyzing dichloromethane extract of smoke particulate by GC/MS. Results showed that total amount of twenty-one acids produced by 20% dilution of cigarette and 25 mm filter cigarette were reduced by 22.1%,26.3% compared with a reference cigarette respectively.Reducing level of each acid is different.The acids with lower molecular weight or lower boiling point dropped more obviously compared with acids which have higher molecular weight or higher boiling point.
