摘要：

Pretreatment techniques were compared.A GC-MS method has been developed for the determination of the residues of seven indicator polychlorinated biphenyls in plant oil.Samples were dissolved with 2 mL n-hexane,and purified by acidification silica-gel column,mixed-metal silica-gel column,and alumina base,respectively.The eluent was concentrated and 1 mL n-hexane was added.And the analytes were determined by GC-MS using PCB 198 as an internal standard.The spiked recoveries were 89%-115%.The relative standard deviations were range of 4.87%-10.3%.The limits of detection were 0.2-1.0 μg/kg.
