建立了气相色谱–串联质谱法测定塑料食品包装材料中抗氧化剂二丁基羟基甲苯(BHT)、丁基羟基茴香醚(BHA)和特丁基对苯二酚(TBHQ)残留量的分析方法。样品采用环己烷–乙酸乙酯混合溶剂超声萃取，经固相萃取法富集和净化，采用气相色谱–串联质谱在多反应监测模式下进行测定。结果表明，3种抗氧化剂质量浓度在0.05～20 mg／L 范围内线性关系良好，线性相关系数大于0.999；BHT，BHA，TBHQ 的检出限分别为0.005，0.01，0.03 mg／kg ；平均添加回收率为88.7%～104.0%；测定结果的相对标准偏差小于5.5%(n=6)。该方法操作简便，灵敏度高，重复性好，可用于塑料食品包装材料中抗氧化剂 BHT，BHA，TBHQ 残留量的测定。

A new method for the simultaneous determination of three antioxidant residues (butylated hydroxytoluene, butylated hydroxyanisole,tertiary butylhydroquinone)in food plastic packaging materials by solid phase extraction–gas chromatography–tandem mass spectrometry(GC–MS/MS) was developed. The antioxidants were extracted from the samples with cyclohexane-ethyl acetate in the assistant of ultrasonic extraction,and then enriched and cleaned-up with solid phase extraction on a silica column. The detection was carried out by GC–MS/MS in the single-reaction monitoring (SRM) mode. The calibration curves showed good linearity in the range of 0.05–20 mg/L with the correlation coefficients more than 0.999. The detection limits were 0.005,0.01 and 0.03 mg/kg for BHT,BHA and TBHQ,respectively. The average recoveries of the three antioxidants in commercial food plastic packaging materials were 88.7%–104.0%,the relative standard deviations were less than 5.5%(n=6). This method is simple,sensitive,highly reproducible,and suitable for determination of three antioxidant residues in food plastic packaging materials.
