| 摘 要： | 利用高效液相色谱-串联质谱法检测大豆及土壤中喹禾糠酯和代谢物喹禾灵酸的残留及消解动态。样品用盐酸混合液和乙腈提取,石墨炭黑和C18填料净化,高效液相色谱串联质谱法检测,外标法定量。结果表明,喹禾糠酯及代谢物喹禾灵酸在大豆植株、籽粒、毛豆、土壤中的添加平均回收率分别为82.4%~95.3%、90.4%~101.9%,相对标准偏差分别为2.8%~10.3%、2.1%~10.9%。喹禾糠酯及代谢物喹禾灵酸在大豆籽粒上定量限为0.01mg/kg,在大立植株、毛豆和土壤中的定量限为0.005mg/kg;喹禾糠酯及代谢产物喹禾灵总量的消解半衰期在大豆植株上为7.0d,在土壤上为1.7d和2.0d,在毛豆和大豆中的最终残留量分别为<0.005mg/kg和<0.01 mg/kg。
