摘要
运用玻纤滤膜及GDX—101采得燃油烟空中气态及颗粒物中为环芳烃(PAHs),经CH_2Cl_2提取后,通过GC/MS对提取液分析,对十五种多环芳烃进行了定性及半定量。结论指出废油燃烟中多环芳烃的污染是相当严重的。
A procedure for determination of PAHs in waste oil fired flue gas was presented; including sampling (smoke particulates and gaseous PAHs), extraction and analysis by using SE-54 capillary GC column. Fifteen PAHs Were identified by GC/MS and quantitatively determined by GC/FID. Internal standards method Was used to determine the peak area. It was found that the concentrat-ons of PAHs were higher in smoke particulates than in flue gas. The concentr-tion of benzoa-pyrene (B[a]P) were 1.27-30.05μg/m3 and 0.29-1.15μg/m3 in smoke particulate and in gas respectively.
