【摘要】 采用甲醇/浓盐酸浸渍振荡提取,二氯甲烷萃取、经弗罗里硅土柱层析净化,用液相色谱法测定.方法的最低检出含量为0.02mg/kg,添加回收率在95. 8%～96.6%之间.更多还原

【Abstract】 Method for determining femesafen residue in soil was described. The soil sample was soaked overnight in methanol and hydrochloric acid solution, then extracted with dichlorme - thane, cleaned up with chromatography column, and quantified by reverse phase liquid chromatography. Detection limit was 0. 02mg/L. Recovery rate was 95. 8%-96. 6%.更多还原
