以气相色谱法附火焰光度检测器(FPD)对市售颗粒饲料、粉状饲料中的敌敌畏、甲胺磷等16种有机磷农药进行了残留分析。得出结果:16种有机磷农药均在20分钟内流出,分离效果良好。加标回收率:72.4%~89.2%;变异系数(RSD):1.67%~4.19%;标准曲线相关系数:0.9910~0.9996,符合农药残留分析方法的要求。 The residue analysis of 16 organophosphorus pesticides such as dichlorvos and methamidophos in commercial pellet feed, powdered feedstuff and gas chromatograph with flame photometric detector (FPD) was carried out. The results show that: 16 kinds of organophosphorus pesticides are out within 20 minutes, the separation effect is good. The spiked recoveries ranged from 72.4% to 89.2%. The coefficients of variation (RSDs) ranged from 1.67% to 4.19%. The correlation coefficients of standard curves ranged from 0.9910 to 0.9996, which met the requirements of pesticide residue analysis methods.
