【摘要】：样品经水、4%(体积分数)乙酸溶液、20%(体积分数)乙醇溶液、50%(体积分数)乙醇溶液等4种食品模拟物浸泡后,浸泡液用0.45μm滤膜过滤。采用Agilent Eclipse XDB-C18色谱柱(250mm×4.6mm,5μm)分离待测物,以乙腈-水混合液为流动相进行梯度洗脱,采用二极管阵列检测器分别在259,228,247nm处测定双酚S、双酚A和4,4′-二氯二苯砜。双酚S、双酚A和4,4′-二氯二苯砜的线性范围均为0.02~5.0 mg·L~(-1),检出限(3S/N)分别为0.01,0.02,0.01mg·L~(-1)。加标回收率在89.6%~103%之间,测定值的相对标准偏差(n=6)在0.84%~3.2%之间。
[Abstract]:The sample was soaked in 4 kinds of food mimics, such as water 4% (volume fraction) acetic acid solution 20% (volume fraction) ethanol solution 50% (volume fraction) ethanol solution, and the soaking solution was filtered by 0.45 渭 m filter membrane. The sample was separated by Agilent Eclipse XDB-C18 column (250mm 脳 4.6 mm ~ 5 渭 m). The mixture of acetonitrile and water was used as the mobile phase for gradient elution. Bisphenol S, bisphenol A and 4H 4N 4-dichlorodiphenylsulfone were determined by diode array detector at 259228247nm. The linear range of bisphenol S, bisphenol A and 4 chloridiphenyl sulfone is 0.02n 5.0 mg L ~ (-1), and the detection limit (3S/N) is 0.01g / L ~ (-1). The recoveries were between 89.6% and 103%, and the relative standard deviation (nc6) of the determination values was between 0.84% and 3.2%.
