摘要
A method for the determination of Polychlorinated Biphenyls(PCBs) in drinking water by gas chromatography was established.Determination parameters are discussed and optimized in this paper.The method is compared to the classical liquid-liquid extraction method.By the method,84 PCBs were extracted from drinking water.The detection limits of the method for 84 PCBs ranged from 1.2 to 15.0 ng/L,and the average recoveries ranged from 74.8% to 126.8% with relative standard deviation(RSD) of 1.1%-14.8%.This method can be applied to the routine analysis of PCBs in water samples and has the advantages of simultaneous extraction for multi samples,is a rapid process,and produces less pollution with more cost effectiveness.
