| 摘 要： | 目的 为清除苹果中残留农药，确立苹果中克菌丹残留量的毛细管气相色谱分析方法。方法 苹果样本用丙酮及二氯甲烷提取后，再萃取到石油醚中，经硅胶柱净化后采用气相色谱法测定。结果 该方法最低检出浓度为0．006mg／kg，添加回收率分别为：全果95．3％～105．9％；果皮99．0％～104．5%；果肉98．2％～104．3％；土壤101．0％～103．8％。结论 方法简便、快速、准确，各项指标均符合残留分析的要求。

| Abstract: | AimThe analytical method for Captan residue in apple and soil was established.MethodsAfter liquid-liquid separation with petroleum ether, silica gel column was used for cleanup. Capillary gas chromatography was employed for detection.ResultsThe limit of determination was 0.006 mg/kg. The recovery ranged from 95.3% to 105.9% in whole fruit, from 99.0% to 104.5% in apple peal, from (98.2)% to 104.3% in apple flesh, from 101.0% to 103.8% in soil.ConclusionThe method is sensitive and has a good recovery. |
