摘要
In this paper,a GC-MS method for the determination of chlorfenapyr in beef was described.The residue was extracted with acetonitrile,purified by alumina oxide neutral column,and cleaned up with auto solid phase.The chlorfenapyr residue was determined by GC-MS.The results indicated that the detection limit was 0.005 mg/kg,recoveries and RSDs of the method were 93%-100% and 3.4%-7.2%,respectively.The method showed high efficiency and sensitivity,as well as good stability and veracity.
