摘要: 试验研究了鸡肌肉和肝脏组织中10种有机磷农药残留的气相色谱-火焰光度检测方法。用丙酮和二氯甲烷混合溶剂提取,磷酸缓冲溶液沉淀蛋白质等,凝胶色谱法去除剩余油脂等,用配有火焰光度检测器的气相色谱仪检测,外标法定量。在0.05、0.2、1 mg/kg添加水平,肌肉组织的平均添加回收率在74.2%~108.0%,变异系数在1.6%~17. 3%之间。肝脏组织的平均添加回收率在69.8%~103.0%,变异系数在1.0%~16.0 %之间。

Abstract: A method for the determination of organophosphorus pesticide residues in muscle and liver of chicken by GCFPD was described in this paper. Samples were extracted with acetone/ dichloromethane (3∶4) mixture, added PBS(pH=7.4) to deposit protein. Some fats and hydrophobic impurities were removed by gel permeation chromatography (GPC). The sample was analyzed by flame photometric detector (FPD), through a capillary column of DB17. The residues were quantified by external standard method. In this method the recoveries(spiked at 0.05, 0.2, and 1 mg/kg) were 74.2%~108.0% for muscle, 69.8%~103.0% for liver. Coefficients of variation were 1.6%~17. 3% for muscle, 1.0%~16.0 % for liver, respectively.

Key words: organophosphorus pesticide; GCFPD; residues; chicken tissue
