| Abstract: | The method for the determination of 19 polychlorinated biphenyls(PCBs) in water samples was established by gas chromatography-mass spectrometry(GC/MS) with solid phase extraction(SPE).The method had relative high sensitivity and good linearity,and the correlation coefficients were great than or equal to 0.9970,and the detection limits were in the range of 2.34—7.33ng/L,then the recoveries were between 82.3%—103.2%.The method is suit to determine the PCBs in the water samples. |
