摘　　要：为了测定卷烟滤嘴中邻苯二甲酸酯(PAEs)的含量,考察了萃取方式、萃取溶剂、超声条件和检测条件对测定结果的影响,建立了同时测定卷烟滤嘴中17种PAEs的方法,并采用该方法检测了45个卷烟滤嘴中的PAEs。结果表明:①用水、乙醇和正己烷超声萃取30 min效果较好;②该法的回收率为87.0%～105.8%,RSD为2.6%～5.4%;③45个卷烟滤嘴样品中,有14个样品中检出PAEs,总检出率为31.11%。其中,4个样品中检出邻苯二甲酸二正丁酯,检出率8.88%;7个样品中检出邻苯二甲酸二异丁酯,检出率15.56%;8个样品中检出邻苯二甲酸二(2-乙基)己酯,检出率17.78%。该方法适用于卷烟滤嘴中PAEs的同时测定。A method for simultaneously determining 17 phthalic acid esters （PAEs）in cigarette filter was established with GC/MS. The parameters such as extraction mode, extraction solvent, extraction condition, detection condition were tested, and 45 cigarette samples were detected. The results showed that： 1）ultrasonic extraction with water and ethanol mixture for 30 minutes was effective;2）the recoveries of the 17 PAEs ranged from 87.0% to 105.8% with the relative standard deviations（RSDs）of 2.6% to 5.4%; 3）PAEs were found in 14 samples, the detectable rate was 31.11%, in which dibutyl phthalate（DBP）was found in 4 samples with the detectable rate of 8.88%; diisobutyl phthalate（DIBP）was found in 7 samples with the detectable rate of 15.56%; and di（2-ethylhexyl）phthalate（DEHP）was found in 8 samples with the detectable rate of 17.78%. This method is suitable for simultaneously determining PAEs in cigarette filter.
