醋纤和改性丙纤滤嘴对卷烟烟气成分的影响比较

Effects of Cellulose Acetate and Modified Polypropylene Filters on Chemical Components in Cigarette Smoke

摘要: 采用气相色谱/质谱法对改性烟用聚丙纤维(PP)滤嘴和二醋酸纤维(CA)滤嘴卷烟烟气成分进行了对比分析。结果表明,个别PP滤嘴的降焦效果虽然已经接近CA滤嘴,但其降低烟气有害成分的能力明显不如CA滤嘴。

Abstract: The chemical components in mainstream smoke of cigarettes with modified polypropylene (PP) filter or cellulose acetate (CA) filter were analyzed with GC/MS and compared.The results indicated that the contents of hazardous substances in PP filter cigarette smoke were obviously higher than those in CA filter cigarette smoke, although the tar reducing efficiencies of some PP filters were close to those of CA filters.
