| 摘 要： | 建立气相色谱法测定香蕉和土壤中苯醚甲环唑残留量的分析方法。样品经乙腈萃取,采用气相色谱法-氮磷检测器(GC-NPD)进行测定。方法的检出限为0.010 mg/kg,在0.02、0.20、1.00 mg/kg 3个添加水平,香蕉回收率为82%～105%,相对标准偏差为7.4%～10.7%;土壤回收率为80%～104%,相对标准偏差为5.1%～9.3%。方法的重复性较好。

| Abstract: | A method for the determination of difenoconazole residue in fruits was established with GC-NPD. Residues of difenoconazole were extracted from sample with acetonitrile. The final extract was injected into GC with NPD. The detection limit was 0.010 mg/kg. Precision and recovery tests were made at the spike level of 0.02, 0.20, 1.00 mg/kg. The results of banana and soil were as follows: recoveries in the range of 82%~105% and 80%~104%, relative standard deviation 2.14%~5.51% and 5.1%~9.3%. |
