摘　　要：邻苯二甲酸二烯丙酯(DAP)是塑料饭盒中常见的增塑剂,含量超标会影响人的身体健康。先将塑料饭盒机械粉碎为粉末状细小颗粒,以环己烷为提取液,超声辅助萃取塑料饭盒中的邻苯二甲酸二烯丙酯,最后采用气相色谱-质谱联用仪(GC-MS)进行检测。研究表明:该检测方法检出限低,准确度和精密度高,且具有较高的回收率和较好的重现性。完善了现有的邻苯二甲酸二烯丙酯检测方法。Diallyl phthalate(DAP)is a common plasticizer used in plastic lunch boxes.Excessive amount will affect people's health.In this paper,the plastic lunch box was mechanically crushed into fine powder particles.Cyclohexane was used as the extraction solution to extract diallyl phthalate from the plastic lunch box with ultrasonic assistance.Finally,gas chromatography-mass spectrometry(GC-MS)was used for detection.The results show that the method has low detection limit,high accuracy and precision,high recovery and good reproducibility.The existing methods for the determination of diallyl phthalate were improved.
