摘要

以硅胶固载离子液体作为分散剂，采用基质固相分散法萃取/高效液相色谱法检测禽肉和肝脏样品中的8种磺胺类化合物（磺胺二甲基嘧啶、磺胺噻唑、磺胺-6-甲氧嘧啶钠、磺胺氯哒嗪、磺胺异噁唑、磺胺二甲氧嘧啶、磺胺苯吡唑、磺胺硝苯）。基质固相分散最佳提取条件为：含12% 1-己基-3-甲基咪唑六氟磷酸盐（［Hmim］PF6）的硅胶固载离子液体为分散剂，石油醚为淋洗剂，甲醇为洗脱剂，样品与分散剂的质量比为1∶4。8种磺胺类药物在25-1 000 μg/kg范围内线性关系良好（r≥0.997 4），检出限和定量下限分别为4.4-7.6 μg/kg和14.7-25.3 μg/kg，加标回收率和相对标准偏差分别为66.2%-98.7%和1.4%-9.0%。与其他方法相比，本法的样品用量少，操作简单，目标物的检出限和定量下限低，完全可用于禽类产品中磺胺类药物残留量的检测。
