摘要
介绍了用高效液相色谱法测定荞头中氟乐灵农药残留量的方法,样品经正己烷均质提取,过弗罗里硅土小柱后,RP-HPLC分离测定,外标法定量,方法的测定下限为0.025mg/kg,回收率>74%,相对标准偏差<8%。
A method for determination of trifluralin in garlic by HPLC was developed. The trifluralin residues in sample wasextracted by n-hexane. The extract was cleanup by Florisil Column. A HPLC column of SUPELCO Discovery RP-AmideC16(25cm×4.6mm ID, 5μm)was used with elution (0.5ml/min), MeOH-H2O for detection by HPLC-UV, resulted in a detectionlimit of 0.025mg/kg in garlic, a recovery>74% and a coefficient of variation<8%.
