| 摘 要： | 目的]建立一种同时测定蔬菜中噻菌灵和苯菌灵残留量的方法。方法]样品采用酸性甲醇提取,提取液经LC-SCX固相萃取小柱净化,以甲醇-甲酸（0.05%）为流动相,配备Symmetry-C18柱、紫外检测器（280 nm）的高效液相色谱仪对待测组份进行了分离和测定。结果]噻菌灵在蔬菜样品中的添加回收率在77.2%～102.0%之间,变异系数（RSD）小于10%;苯菌灵在蔬菜样品中的添加回收率在75.4%～96.6%之间,变异系数（RSD）也小于10%,均满足残留分析要求,噻菌灵和苯菌灵在样品中的最低检出浓度为0.01mg/kg。结论]本方法操作过程简单快速,重复性好,能满足蔬菜中噻菌灵和多菌灵残留量同时检测的要求。 |
