目的:建立食品用纸制容器中16种多环芳烃的气相色谱-质谱联用的检测方法.方法:采用水、4％乙酸、20％乙醇、正己烷四种模拟食品溶剂浸泡一次性纸杯,用二氯甲烷超声提取浸泡液中的多环芳烃,气相色谱-质谱联用法进行定性定量分析.结果:16种多环芳烃在25 min内流出,分离良好,在0.01 mg/L～ 10.0 mg/L的浓度范围内线性良好,相关系数为0.9985 ～0.9999,方法的检出限为0.24 μg/L ～ 3.80 μg/L(S/N =3),样品的加标回收率为75.9％ ～ 123.1％,相对标准偏差为1.17％ ～ 13.9％.结论:该方法操作简便,准确度高,适于食品用纸质容器中多环芳烃的迁移研究及检测.
Objective; To establish a method for determination of 16 PAHs in paper containers for food by gas chromatography - masss spectrometry. Methods; The disposable paper cups were soaked with water, 4% HAc, 20% ethanol and n - hexane respectively, and the PAHs were extracted with CH2C12 ultrasonically from the four soaking solutions, and then determined by GC - MS. Results; The linearity of the method was good within the range of 0. 01 μg/ml ~ 10. 0 μg/ml for 16 PAHs. Linear correlation coefficients varied from 0. 9985 to 0. 9999. Limits of detection ( LODs) ranged from 0. 24 to 3. 80μg/L. The average recoveries were 75. 9% ~ 123.1% , with the relative standard deviations (RSDs) of 1.17% ~13.9%. Conclusion; The method is simple, accurate and suitable for determining 16 PAHs in the paper containers for food.
