摘要
采用气相色谱法氮磷检测器测定鱼肉和内脏中的久效磷含量。鱼肉或内脏匀浆后 ,用正己烷洗涤 ,二氯甲烷提取 ,以内标法定量分析 ,方法简单 ,灵敏 ,准确。当取鱼组织 0 5 g时 ,方法检测限为 0 0 0 2mg/kg ,加标回收率为 72 6 %～83 3% ,相对标准差在 3 3%～ 7 0
Monocrotophos level of fish muscle and viscera was determined with GC. Fish muscle and viscera was homogenated, washed by n hexane, extracted by dichloromethane, quantitatively analyzed with internal standard method. This method was simple, sensitive and corrective. When the fish muscle was 0.5 g, detection limit was 0.002 mg/kg, sampling recovery rate was between 72.6%～83.3%, relative standard deviation was between 3%～7%.
