| 摘 要： | 目的 建立采用加速溶剂萃取-气相色谱检测鱼粉中7种指示性多氯联苯残留的方法。方法 采用加速溶剂萃取法, 以正己烷-二氯甲烷(1:1, V:V)为提取剂对鱼粉样品进行提取, 提取温度为120 ℃, 压力为10 MPa, 静态提取时间为8 min, 循环提取2次。用浓硫酸进行净化后, 用气相色谱法进行分析测定。结果 多氯联苯在5~500 ng/mL浓度范围内线性关系良好, 相关系数为0.9986~0.9999, 方法定量限为3.0~5.0 μg/kg, 3个添加水平的平均回收率为85.5%~104%, 相对标准偏差为2.61%~8.26%。结论 本方法精密度好, 准确度高, 操作简单、快速, 适用于鱼粉中多氯联苯的定量检测。
