【摘要】 本文建立了高效液相色谱法测定油菜中精唑禾草灵的残留分析方法,避免了气相色谱法中必须的乙酰衍生化反应,具有步骤简单,精确度高的优点。精唑禾草灵(fenoxaprop-P-ethyl)及其代谢物(fenoxaprop-P),在0.1～0.5mg/kg添加浓度范围内,油菜茎叶、籽、土壤样品中回收率为75.02%～108.73%,变异系数为2.098～18.47%。更多还原

【Abstract】 An analytical method for determination of fenoxaprop-P-ethyl residue in rape and soil with HPLC was discribed in this paper.There wasn ’ t steps of derivation with acetyl which was needed in GC method.The ecoveries of fenoxaprop-P-ethyl and fenoxaprop-P in spiked rape leaves,rapeseed and soil samples ranged from75.02%to108.73%(C.V2.098～18.47%) ?更多还原
