| Abstract: | A simply and rapid method has been established for the determination of durene residue in vegetables by solid-phase extraction and GC-MS.The sample was extracted with acetonitrile,and cleaned up on a Florisil column,and detected by the internal standard method with GC-MS.The lowest detectable concentration in samples was 0.005 mg/kg.Samples recoveries ranged from 81.0%～110.0%.The coeficients of variation was 1.03%～3.89%. |
