Abstract
A method to determine BkF, BaP, BbF, BpR and InP in the water Samples was established by liquid- liquid extraction and Envi-Disk SPE-GC/MS. Disc solid phase gathers using the membrane filter form plate shape structure,Cross-sectional area increased and backpressure reduce, can using the higher velocity, can prevent the jams. The chromatogrphy obtained from capillary column was used to improve the qualification. In order to reduce effect of the interfere and intensify response of MS, detection SIM was optimized The limits of determination method for BkF, BaP, BbF, BPR, InP were 6ng/L. GC/MS analysis of concentration in 2.5 ng/mL-62.5 ng/mL, the linearity of five PAHs was in 0.9987%-0.9994% between. Spiked with standard at three levels（6.25ng/L-62.5 ng/L）（n=5）, the recovery rate of five PAHs was in 83.71%-94.38%. The relative standard deviation （RSD） was in 5.44%-15.54%.关键词
