目的：检测两种萃取溶剂对塑料食品包装材料上有机污染物检测效果的影响。方法分别以正己烷和无水乙醇为萃取溶剂对塑料食品包装材料上污染物进行超声提取,提取后用旋转蒸发浓缩,最后采用气相色谱-质谱联机(GC-MS)分析方法以离子化方式对浓缩的污染物进行表征。结果正己烷作为萃取溶剂能萃取出抗氧化剂2,6-二叔丁基对甲酚、增塑剂邻苯二甲酸二丁酯、油墨生产中所用的溶剂正十六烷；乙醇作为萃取溶剂能萃取出抗氧化剂2,6-二叔丁基对甲酚、油墨生产中所用的溶剂正十六烷和正二十烷。结论正己烷作为萃取溶剂的提取效果要比乙醇作为萃取溶剂提取效果好。

Objective To observe the effect of the two kinds of extraction solvent on the detection of organic pollutants in plastic food packaging materials. Methods The residual contaminants were extracted by n-hexane and ethanol from plastic food packaging materials under ultrasonic condition, concentrated by rotary evaporator, and finally analyzed by gas chromatography-mass spectrometry (GC-MS). Results 2,6-di-tert-butyl-4-methylphenol (BHT), plasticizer dibutyl phthalate (DBP) and n-hexadecane solvents in printing ink were obtained using n-hexane as extraction solvent. While antioxidants 2,6-di-tert-butyl-4-methylphenol (BHT), n-hexadecane and n-eicosane were obtained using ethanol as extraction solvent. Conclusion The extraction effect using n-hexane as extraction solvent is better than that using ethanol as the extraction solvent.
