Abstract
为测定烟用水基胶中的柠檬酸三丁酯(TBC)和乙酰柠檬酸三丁酯(ATBC),分别用正己烷、环己烷、乙醚、异辛烷进行了萃取烟用水基胶中TBC和ATBC试验,并采用气相色谱-质谱(GC/MS)/选择离子监测(SIM)法测定了烟用水基胶中的TBC和ATBC.结果表明:①以正己烷为萃取溶剂,0.3 g胶样中加入2 mL水,萃取体积10 mL,振荡30 min萃取效果较好.②方法线性关系良好,线性相关系数均大于0.99；TBC和ATBC的检出限分别为0.26和0.20 μg/mL；回收率和RSD分别为96％～ 107％和3.93％～4.12％.该方法适用于烟用水基胶中TBC和ATBC的测定.
