摘要
本文介绍了一个简单、可靠的大豆中除草剂"卫农"残留测定方法。样本用蒸馏法提取后不需要纯化即可用带火焰光度检测器的气相色潜仪直接测定。方法最低检出浓度0.025ppm。方法回收率81.0%~97.2%。
This paper deals with a simple and reliable residue analysis method of herbi- cide 'Vernolate' in soybeans.'Vernolate' was seperated from soybean samples by steam distillaton.The purification process of sample extract was omitt-ed. The isolated 'Vernolate' was determined by using gas chromatography equipped with FPD-detector.The limit of detection of the method is 0.025 ppm.The recoveries of the method are 81.0%~97.2%
