非邻苯酯类增塑剂在卷烟中的转移行为

为研究非邻苯二甲酸酯类增塑剂在卷烟主流烟气的转移行为,将12种非邻苯酯类增塑剂添加到卷烟烟丝中,利用剑桥滤片捕集卷烟主流烟气,剑桥滤片和烟蒂分别经二氯甲烷萃取后,使用GC/MS/SIM分析各非邻苯酯类增塑剂在主流烟气的转移率和烟蒂的截留率。结果表明:12种非邻苯酯类增塑剂在主流烟气的转移率在7.86%～15.11%之间;12种非邻苯酯类增塑剂在烟蒂中的截留率在18.65%～36.54%之间;非邻苯酯类增塑剂在烟蒂中的截留率明显高于在主流烟气中的转移率,其中己二酸二乙酯在主流烟气中的转移率最低,而在烟蒂中截留率最高。

Transfer Behavior of Non-Phenyl Ester Plasticizers in Cigarettes

To study the transfer behavior of non-phenyl ester plasticizers in cigarette mainstream smoke, add 12 non-phenyl ester plasticizers to cigarette cut tobacco, and use Cambridge filters to capture mainstream cigarette smoke, Cambridge after the filter and the cigarette butts were extracted by dichloromethane, the transfer ratio of the non-phenyl ester plasticizer in the mainstream smoke and the rejection ratioof cigarette butt were determined by GC/MS/SIM. The results show: The transfer ratio of 12 non-phenyl ester plasticizers in mainstream smoke was 7.86 % ~ 15.11%; The retention ratio of 12 non-phenyl ester plasticizers in cigarette butts was 18.65 % ~ 36.54 %; The rejection ratio of non-phenyl ester plasticizers in cigarette butts is significantly higher than the transfer ratio of non-phenyl ester plasticizers in mainstream smoke.The transfer ratio of diethyl adipate in mainstream smoke is the lowest, while the rejectionratio of cigarette butts is the highest.
