摘 要:建立了纺织品与食品包装材料中烷基酚及双酚A迁移量的液相色谱-串联质谱分析方法。纺织品和食品包装材料浸泡液经Supelclean Envi—Carb石墨化碳黑固相萃取柱净化,以Waters XBridgeC.8(150mm×2.1mm,3.5μm)色谱柱分离后,进行LC—MS/MS多反应监测模式下的定性及定量分析。烷基酚和双酚A在纺织品模拟汗液、食品模拟物介质中特定迁移量的定量下限分别为2、4肛g/kg。在低、中、高3个添加水平下,测得纺织品样品的回收率为83%~91%,相对标准偏差为4.1%~9.0%;食品包装材料样品的回收率为82%~94%.相对标准偏差为3.9%-8.7%。A comprehensive analytical method based on liquid chromatography --tandem mass spectrometry has been developed for the determination of alkylphenols and bisphenol A migration from textiles and food packaging materials. The migration of alkylphenols and bisphenol A from textile samples to artificial perspiration was studied by stirring extraction at 60 r/min in a 37 ℃ water bath for 30 min. The food packaging material samples were soaked by four simulants, including water, 3% (by volume) acetic acid, 10% (by volume) ethanol and isooctane using the simulated contact temperature and time. The extract was cleaned up on a Supelclean Envi-Carb solid phase extraction cartridge and separated on a Waters XBridge C18 ( 150 mm × 2. 1 mm, 3.5 μm) column. Qualitative and quantitative analyses of the analytes were (LOQs) for alkylphenols and bisphenol A were 2 μg/kg and 4 μg/kg, respectively. rials at three spiked levels were 83%-91% carried out under MRM mode. The limits of quantitation specific migrations from textiles and food packaging materials The mean recoveries from textiles and food packaging and 82%-94% , respectively, with RSDs of 4. 1%- mate- 9. 0%and 3.9% - 8. 7% , respectively.
