摘  要:
采用高效液相色谱-串联质谱法,建立了吡嘧磺隆在稻田水、土壤、动态植株、稻秆、稻壳、稻米等6种基质中的残留检测方法。样品采用乙腈提取,C18净化,HPLC-MS/MS检测。结果表明,吡嘧磺隆在上述6种基质中的添加回收率在77.7%~105.0%之间,相对标准偏差在0.9%~7.0%之间,定量限(LOQ)为0.001~0.01 mg/kg。方法符合农药残留检测要求。

摘  要:
A high performance liquid chromatograghy-tandem mass spectrometry(HPLC-MS/MS) method was established to determine the residue of pyrazosulfuron-ethyl in rice. The samples were extracted with acetonitrile, cleaned up by C_(18). The average recoveries of pyrazosulfuron-ethyl in paddy water, paddy soil, rice plant, rice straw, rice husk and brown rice were 77.7%-105.0%, with the relative standard deviations of 0.9%-7.0%. The limits of quantification(LOQ)were 0.001-0.01 mg/kg.
