气相色谱法测定蔬菜中多种有机磷农药

Gas Chromatography Mensurates Multifold Organic Phosphate Pesticide

探讨同时测定蔬菜中多种有机磷农药残留量的方法。蔬菜样品经前处理后用气相色谱仪测定甲胺磷、敌敌畏、乙酸甲胺磷、氧化乐果、甲拌磷、乐果、马拉硫磷和对硫磷等8种有机磷农药残留量,测定了方法的回收率和精密度,分析了干扰情况。上述8种农药的平均回收率分别为99.0%,96.0%,130.4%,101.3%,95.9%,99.4%,92.4%,91.0%,变异系数分别为6.91%,6.09%,9.23%,9.63%,9.18%,7.01%,6.82%,7.50%。该方法操作简便,回收率和精密度较好,干扰少。

To study A Method For Simultaneous Determination Of Organophosphorus Pesticide Residues In Vegetables. The Contents Of Methamidophos, Dichlorvos, Aeephate Dimethoate, Alathion And Parathion In The Pre - Treated Vegetable Samples Were Determines. The Recovery Rate And Accuracy Of The Method Were Analyzed. The Recoveries Of Methamidophos, Dichlorvos,Acephate, Omethoate, Phorate, Dimethoaste, Alathion And Parathion Were 99.0% ,96.0% , 130.4% , 101.3% ,95.9% ,99.4% , 92.4% And 91.0% Respectively,The Coeftleiems Of Variation Were 6.91% , 6.09% ,9.23% ,9.63% ,9.18% ,7.01% ,6.82% And 7.50% Respectively. The Method Was Simple With The Better Recovery Rate And Accuracy And Less Interfering Factors.
