| Abstract: | A capillary gas chromatographic method with an electron capture dector(ECD) for the detection of polychlorinated biphenyls(PCBs) in seawater was developed.It was done with liquid-liquid extract,basic decomposition,silica gel cleanup,concentration,etc to treat the samples,identified and quantified the PCBs with GC-ECD.The recoveries of the PCBs were between 84.1% and 101.5%.The relative standard deviations were less than 4.8%.The method presented the advantages of high precision,high sensitivity and high recovery.The method can be used to analyze PCBs in seawater. |
