摘要
建立了固相萃取-气相色谱-质谱联用选择离子扫描法同时检测水样中19种多氯联苯(PCB s)的方法。该法对水样中PCB s的检测具有较高的灵敏度和较好的线性,其相关性r≥0.9970,检出限为2.34—7.33ng/L、回收率为82.3%—103.2%,适用于水样中多氯联苯的测定。
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.
