【摘要】 通过二次柱层析纯化和富集卷烟烟气中多环芳烃 ,用气相色谱 /质谱法进行多环芳烃的定性和定量分析。在卷烟烟气中检测了蒽 ,菲 ,荧蒽 ,芘 ,苯并 [a]蒽 , ,苯并荧蒽 ,苯并 [e]芘 ,苯并[a]芘等多环芳烃 ,其浓度在 8～ 391 ng/支之间 ,多环芳烃回收率在 80 %以上。在此基础上测定了 3种不同焦油含量的卷烟烟气中的多环芳烃 ,发现卷烟烟气中多环芳烃含量与焦油含量有良好的相关性更多还原

【Abstract】 Polycyclic aromatic hydrocarbons (PAHs) in cigarette smoke were purified and enriched using flash column chromatography, and then measured by GC MS. Anthracene, phenanthrene, fluoranthene, pyrene, benzo[a] anthracene, chrysene, benzofluoranthene, benzo[e] pyrene and benzo[a] pyrene in cigarette smoke were analyzed, and their concentrations were found to be 8～391 ng/cigarette. Recovery of PAHs was over 80%. Cigarettes of 3 different tar levels were measured and excellent interdependency was found between PAHs concentration and tar level.更多还原
