| 摘 要： | 介绍一种运用毛细管气相色谱法检测谷物中酰胺类除草剂多残留快速测定方法。采用石油醚作为溶剂提取样品中农药，中性氧化铝的层析柱净化，石油醚／乙酸乙酯（9：1，v／v）洗脱。气相色谱（附ECD检测嚣）检测，用保留时间和外标法定性、定量。对大米样品进行添加回收率实验，分别添加0．50mg／kg、0．20mg／kg、0，10mg／kg、0．05mg／kg、0．02mg／kg。添加回收率在86．5％～109．5％之间，变异系数为3．5％8．1％。

| Abstract: | A method is described for determining 6 herbicides in corn by GC.The residues of herbicides were extracted from samples with petroleum ether and the extractive removed through a neuter alumina column.Then petroleum ether/ethyl acetate(v/v,9/1) eluted it.Herbicides determination was performed with the gas chromatography(with ECD detection).Compounds were identified and determined according to their retention times and the external standard mehthod.Recoveries were obtained by adding 6 herbicides to rice(spiking at 0.50 mg/kg,0.20 mg/kg,0.10 mg/kg,0.05mg/kg,0.02mg/kg levels).The recoveries ranged from 86.5% to 112.5%,and the coefficients of variation was from 3.5% to 8.1%. |
