摘要：

A novel method is presented for the analysis of coplanar (i.e. non-ortho substituted) polychlorinated biphenyls (PCBs) in environmental samples. The new procedure combines methylene chloride extraction, gel permeation and Florisil chromatography. Recovery efficiencies and resolution of the Florisil column method are reported and compared to the carbon column method. It is shown that both the Florisil column and the Carbon column techniques give comparable results with recovery efficiencies for PCBs 77, 126 and 169 of nearly 100%. Excellent resolution and reproducibility for quantitative analysis of coplanar PCBs are obtained in complex PCB mixtures. The Florisil method is considerably simpler than the carbon column technique and better suited for routine analysis.
