摘要:

建立用加速溶剂萃取/ 气相色谱- 质谱法测定糖果包装材料中双酚A 的分析方法。样品用二氯甲烷- 丙酮作提取剂,加速溶剂萃取仪提取,经BSTFA+TMCS 衍生化,用气相色谱- 质谱联用仪进行定性定量分析,双酚A的回收率在75.2%~90.7% 之间、方法的检出限为5μg/kg。该方法前处理过程简单,具有较高的精密度和准确性,重复性好。

Abstract:

An accelerated solvent extraction followed by gas chromatography-mass spectrometric method was presented for determining bisphenol A in candy packaging materials. Samples were extracted with a mixture (7:3, V/V) of dichloromethane and acetone in an accelerated solvent extractor, derivatized with a commercial BSTFA-TMCS mixture prior to GC-MS analysis. Mean spike recoveries of bisphenol A at three levels were between 75.2% and 90.7%, and the limit of detection (LOD) of bisphenol A was 5 μg/kg. This method has the characteristics of simplicity, high accuracy and precision and good reproducibility.

Key words: bisphenol A, accelerated solvent extraction, candy packaging materials, gas chromatography-mass spectrometry (GC-MS)
