| 中文摘要: |
| 建立了气相色谱-质谱(GC-MS)检测食品包装材料表面印刷油墨中光引发剂二苯甲酮(BP)和4-甲基二苯甲酮(MBP)迁移量的方法。样品以正己烷为提取溶剂进行振荡提取和超声波辅助萃取，提取液用GC-MS分析检测。结果表明：该方法线性范围为0.02 ~0.1 mg/mL，检测限为0.004~0.005 mg/mL，在0.01，0.02，0.10 mg/mL 3个添加水平下，2种光引发剂的平均回收率为88.2%~114.5%，相对标准偏差（n=6）为5.13%~7.95%。该方法简单快速，适用于食品包装材料的日常检测需要。 |
| 英文摘要: |
| An analytical method based on gas chromatography-mass spectrometry (GC-MS) tech-niques was developed for determination of benzophenone and 4-methylbenzophenone photoini-tiators in printing inks used for food packaging materials. The test samples were extracted from selected food packaging materials using oscillating extraction and ultrasonic assisted extraction with n-Hexane as the extraction solvent, and the extracts was analyzed by GC-MS. The results showed that the linearity range of the method is 0.02~0.1 mg/mL and the limits of detection for benzophenone and 4-methylbenzophenone are 0.004 mg/mL and 0.005 mg/mL; the average re-coveries of the three adding levels(0.01, 0.02, 0.10 mg/mL) are 88.2%~114.5%, with the relative standard deviations（n=6）of 5.13%~7.95%. It was concluded that the method is simple and rapid, which is applicable for routine determination of food packaging materials. |
