| 摘 要： | 目的建立气相色谱-质谱法(gas chromatography-mass spectrometry,GC-MS)同时测定三文鱼中12种多氯联苯的方法。方法样品经石油醚提取后,用浓硫酸和层析柱进行净化,正己烷洗脱。得到的提取物经DB-5MS色谱柱(30 m×250μm,0.25μm)分离,载气为氦气,流速为1.5 mL/min,温度为270℃。然后采用电子轰击离子源进行质谱测定,全扫描方式采集数据。结果 12种多氯联苯在10.0~000μg/L浓度范围内呈良好的线性关系,相关系数r0.9989,方法检出限为0.3~1.2μg/kg,3个不同加标水平下PCBs的平均回收率为85.5%~99.6%,日内相对标准偏差在3.56%~8.12%范围内。结论该方法灵敏度高、准确度和精密度良好,适用于三文鱼中12种PCBs含量的快速检测。
