  • 摘要: 研究了用气相色谱-质谱检测器同时检测玉米中21种三嗪除草剂多残留量的方法。样品经过乙腈萃取后直接用强阳离子交换柱(SCX)净化并在重力条件下操作,用DB-5MS毛细管柱分离,气相色谱-质谱联用仪进行测定。21种三嗪除草剂在0.01~0.5 μg/mL内线性关系良好。平均添加回收率84.0%~104.1%,相对标准偏差(RSD)0.8%~5.1%,最低检测限为0.01 mg/kg。
    Abstract: A multi-residue method for determination of 21 kinds of triazine herbicides in maize was described. The triazine herbicide residues were extracted with acetonitrile and cleaned up with strong cation-exchange solid-phase extraction column. The extraction was separated by capillary column (DB-5MS, 30 m×0.25 mm ×0.25 μm) and detected by GC/MS. The good linearities were obtained for 21 triazine herbicides. The limits of quantitation were 0.01mg/kg. The average spiked recoveries ranged from 84.0% to 104.1% and the relative standard deviations were between 0.8% and 5.1%.
