| 摘 要： | 以丙酮为提取剂,二氯甲烷为萃取剂,采用弗罗里硅土柱净化,气相色谱-电子捕获检测器测定柑橘和土壤中的螺螨酯残留,优化了样品前处理条件。方法在0.141μg/L～5.65 mg/L范围内线性良好,最低检出限为0.003 5 mg/kg,空白样品在0.050 mg/kg、0.500 mg/kg、1.00 mg/kg 3个添加水平上的平均回收率为82.2%～110%,平行测定的RSD为2.6%～9.8%。

| Abstract: | A method for determining spirodiclofen in orange and soils was established by using GC with ECD,acetone as extractant and methylene dichloride as extractive solution,purification by Florisil cartridge.The results of optimized experimental conditions showed that linearity was good range from 0.141 μg/L to 5.65 mg/L,the minimum detection limits 0.003 5 mg/kg,spiked recoveries at 0.050 mg/kg,0.500 mg/kg and 1.00 mg/kg levels of blank samples from 82.2% to 110%,RSD of duplicates from 2.6% to 9.8%. |
