以茴香脑为内标,采用异丙醇萃取-气相色谱法同时测定烟用接装纸和包装纸中14种邻苯二甲酸酯类化合物残留.该方法的平均回收率为86.5%～111.9%,检测限为0.18～1.48μg/g,相对标准偏差除邻苯二甲酸二环己酯(DCHP)为5.21%外,其余均小于5%.该方法的分离效果好,灵敏度高,能满足烟用接装纸和包装纸中邻苯二甲酸酯类化合物的检测.

Fourteen kinds of phthalate residnes in tipping paper and packing paper of cigarette were determined simultaneously by gas chromatography with anethole as internal standard. Samples were extracted with isopropyl alcohol. The average recoveries of fourteen phthalates were in the range of 86.5%～111.9% with the detection limits of 0.28μg/g～1.45μg/g. The RSDS were 5.21% except dicyclohexyl phthalate (5.21%). The method has good separation capability and high sensitivity, and can meet the requirement for the determination of phthalates in tipping paper and packing paper for cigarette.
