| 摘 要： | 比较3种吡虫啉的残留提取方法，筛选出一种适合于毗虫啉在土壤和茶叶中的残留的提取方法．用高压液相色谱测定茶叶和土壤中吡虫啉残留量：样品经甲醇超声提取，二氯甲烷萃取，用硅胶层析柱净化提取物．此方法经高压液相色谱测定（HPLC），其最小检出量为1．0×10^-9，最低检出浓度为0．01mg·kg^-1，平均添加回收率为80．56％～90．01%，变异系数为0．37％～3．71％．

| Abstract: | A method is developed for the determination of imidacloprid in tea and soil by HPLC in this 1 paper. Imidacloprid was extracted an ultrasonic bath by methylalcohol, and then reextracted by dichloromethane, cleaned up by Florisil column. Imidacloprid will be detected by HPLC technique and a good chromatographic separation. The detectable limit of concentration was 0. 01 mg · kg-1. The recovery for residues determination and variation coefficient was 80. 56%--90. 01% and 0. 37%- 0.3.7% respectively. |
