摘　　要：建立了气相色谱法测定食品接触材料中的12种丙烯酸酯类单体在10%(体积分数)乙醇溶液(A)、4%(体积分数)乙酸溶液(B)、20%(体积分数)乙醇溶液(C)、50%(体积分数)乙醇溶液(D)等4种水性食品模拟物中的特定迁移量的方法。食品模拟液经二氯甲烷旋涡振荡提取(A、B、C中加入氯化钠1.2 g,D中加入饱和硫酸钠溶液0.5 mL),用HP-VOC毛细管色谱柱进行分离,火焰离子化检测器检测。12种丙烯酸酯类单体的质量在2.5~50μg内与其峰面积呈线性关系,检出限(3S/N)为0.05~2.0μg。按标准加入法进行回收试验,测得回收率为84.0%~115%,测定值的相对标准偏差(n=6)为1.0%~9.6%。A gas chromatography method was established for the determination of 12 acrylate monomers amounts migrated from food contact material to 4 kinds of aqueous food simulants,such as 10%(φ)ethanol solution(A),4%(φ)acetic acid solution(B),20%(φ)ethanol solution(C)and 50%(φ)ethanol solution(D).Food simulation solution was extracted by dichloromethane vortex oscillation,in which 1.2 g of sodium chloride was added to A,B and C,as well as 0.5 mL of saturated sodium sulfate solution to D.The extract was separated by HP-VOC capillary chromatographic column,and detected by flame ionization detector.Linear relationships between values of peak area and mass concentration of 12 acrylate monomers were found in the same range of 2.5-50μg,with detection limits(3 S/N)ranging from 0.05 to 2.0μg.Tests for recovery were made by standard addition method,giving results in the range of 84.0%-115%,and RSDs(n=6)of the determined values were ranged from 1.0%to 9.6%.
