| 目的 为测定烟用包装材料中非邻苯二甲酸酯类增塑剂的含量，建立气相色谱-质谱-离子扫描（GC/MS-SIM）技术同时测定烟用包装材料中12种非邻苯酯类增塑剂含量的检测分析方法。方法 采用二氯甲烷溶液为溶剂，振荡萃取烟用包装材料中的目标物，经GC-MS-SIM分析后，以苯甲酸苄酯为内标进行定量。结果 该方法在0.001~0.200 mg/g范围内线性良好，决定系数R2>0.999，检出限范围为1.2~7.2 μg/g，12种非邻苯二甲酸酯类增塑剂的回收率在90.63%~102.99%之间（RSD为0.71%~5.37%，n=5）。运用该方法测定采集到的12种烟用包装材料，检测到了5种非邻苯二甲酸酯类增塑剂，其含量范围分别为己二酸二乙酯（0~0.0200 mg/g）、磷酸三丁酯（0.1699~0.1783 mg/g）、磷酸三苯酯（0~0.0231 mg/g）、乙酰柠檬酸三丁酯（0.0062~9.0358 mg/g）、柠檬酸三丁酯（0~0.0198 mg/g）。结论 该方法便于操作，有较高的灵敏度，可满足快速准确分析的要求，适用于烟用包装材料中非邻苯二甲酸酯类增塑剂含量的检测分析。 |

| Abstract: |
| The paper aims to establish a method for simultaneous determination of 12 non-phenyl ester plasticizers in cigarette packaging materials by GC-MS-SIM to determine the content of non-phenyl ester plasticizers in cigarette packaging materials. The target substance in the cigarette packaging material was extracted by shaking with dichloromethane solution as the solvent, and ana-lyzed by GC-MS-SIM, and then quantified with benzyl benzoate as the internal standard. The results showed that the method had good linearity in the range of 0.001~0.200 mg/g, the determination coefficient R2>0.999, the detection limit range was 1.2~7.2 μg/g, the recovery rate of 12 non-phenyl ester plasticizers was between 90.63% and 102.99% (RSD=0.71% to 5.37%, n=5). This method was used to determine the 12 kinds of cigarette packaging materials collected, five kinds of non-phenyl ester plasticizers were detected, and their content ranges were DEA (0~0.0200 mg/g), TBP (0.1699~0.1783 mg/g), TPP (0~0.021 mg/g), ATBC (0.0062~9.0358 mg/g), TBC (0~0.0198 mg/g). The method is easy to operate, has high sensitivity, can meet the requirements of fast and accurate analysis, and is suitable for detection and analysis of non-phthalate plasticizer content in packaging materials for cigarettes. |
