摘　　要：以丙酮为苹取剂，建立了微波苹取／气相色谱-质谱法（GC-MS）测定纸质食品包装材料中双酚A含量的分析方法。考察了微波革取温度与时间对萃取效果的影响，选择了最佳的微波草取条件。结果表明：方法的检出限为0．05mg／kg，样品的加标回收率为84．2％～95．4％，相对标准偏差小于4．6％。该方法具有快速、方便、灵敏度高等优点，适合于纸质食品包装材料中双酚A含量的快速测定。A method was developed for the determination of bisphenol A in paper packaging material for tbodstuffs by microwave extraction combined with a gas chromatography-mass spectrometry, acetone as extraction solvent, the effects of microwave extraction temperature and time were investigated and optimized. The results show that detection limit is 0.05 mg/kg, the range of 84.2%-95.4% with relative standard deviation（RSD） is below 4.6%. The method is rapid, simple, and accurate, can be used for the test ofpentachlorophenol in paper packaging material for foodstuffs.
