摘  要:为测定烟用水基型乳胶中的邻苯二甲酸酯,用加有内标物质的正己烷溶液对乳胶样品进行了超声萃取,并采用气相色谱/质谱/选择离子监测法(GC/MS/SIM)测定了144个样品中的7种邻苯二甲酸酯:邻苯二甲酸二甲酯(DMP)、邻苯二甲酸二乙酯(DEP)、邻苯二甲酸二异丁酯(DIBP)、邻苯二甲酸二丁酯(DBP)、邻苯二甲酸二(2-乙基己)酯(DEHP)、邻苯二甲酸二辛酯(DOP)和邻苯二甲酸丁基苄基酯(BBP)。结果表明:①样品中加入2 mL水,超声30 min萃取效果较好;②在标准溶液浓度范围内,7种邻苯二甲酸酯的线性均较好,相关系数达到0.996以上;③低、中、高3种浓度的加标回收率在85%~111%之间,相对标准偏差(RSD)均小于5%;④当前国内烟用水基胶中使用的邻苯二甲酸酯类增塑剂主要集中在DIBP,DBP两种。In order to determine the phthalates in water-based emulsion adhesives for tobacco, the adhesives were extracted with n-hexane containing internal standard by ultrasonic instruments. Seven phthalates in 144 water- based emulsion adhesive samples, including dimethyl phthalate ( DMP), diethyl phthalate ( DEP), diisobutyl phthalate ( DIBP), dibutyl phthalate ( DBP), di- ( 2-ethylhexyl ) phthalate ( DEHP), dioctyl phthalate (DOP) and benzyl butyl phthalate (BBP), were determined by gas chromatography/mass spectrometry. The results showed that : 1 ) 30 minutes were preferable duration for extraction by adding 2 mL water into the sample ;2 ) the regression coefficients of the 7 phthalates were over 0. 996 within the range of their calibration ;3 ) the recoveries (the standard spiked at low, middle and high concentration levels) ranged from 85% to 111%, and the relative standard deviation (RSD) of the method was below 5% ;4) DIBP and DBP are the two phthalate plasticizers among the water-based adhesives most commonly used in the cigarette industry.
