摘    要:建立了一种测定食品纸包装材料中多氯联苯的方法。采用超声萃取法提取样品,通过固相萃取柱净化、无水硫酸钠脱水、浓缩后,用气质联用法进行测定。该方法的检出限为10g/kg,回收率为75%~96%,相对标准偏差为2.9%~6.9%。并初步建立了三重串联四极杆气相色谱/质谱/质谱验证方法,该方法的检出限为1μg/kg。

关 键 词:超声萃取  气质联用法  三重串联四极杆气相色谱/质谱  食品纸包装材料  多氯联苯

Abstract:A method for the determination of polychlorinated biphenyls (PCBs) in food packaging papers was establised. The PCSs were extracted by ultrasonic extraction, purified by solid-phase extraction column, and dehydrated by anhydrous sodium sulfate. After being concentrated, the sample was determined by gas chromatography-mass spectrometry. The detection limit was 10gg/kg, the recoveries were 75%-96%, and RSDs were 2.9-6.9%. An authentication method, GC-MS-MS, with the detection limit of 1μg/kg was also established.
