本文提供了一个简单、快速测定烟草中来福灵的残留分析方法。样品经丙酮、石油醚混和液提取，石油醚萃取，经氟罗里硅土层析柱净化，气相色谱ＥＣＤ检测，回收率为８７．５１％～９７．７９％，最低检出浓度为０．００１４～０．００７ｍｇ／ｋｇ。据１９９２、１９９３年来福灵在烟叶中消解动态试验表明：两年两地的降解曲线均呈指数型，施药２５天降解率均在９０％以上。两年两地的最终残留试验表明：在同等剂量情况下，山东的残留量高于云南，说明来福灵的消解与土质、气温、降雨量及植株长势有一定影响
This article provides a simple and rapid method for the determination of Raffling in tobacco. The samples were extracted with acetone and petroleum ether and extracted with petroleum ether. The samples were purified with Florisil silica column and detected by gas chromatography with ECD. The recoveries were 87.51% ~ 97.79%, and the lowest detection limit was 0. 0014 ~ 0.007mg / kg. According to the 1992 and 1993 years, the dynamic test of Fuling in the tobacco leaf digestion showed that the degradation curves of the two years showed exponential type, and the degradation rate of the fumigation was above 90% in 25 days. The final residue test in two years showed that the residual amount of Shandong was higher than that of Yunnan at the same dose, indicating that the digestion of Lafuling had some influence on soil quality, temperature, rainfall and plant growth
