【摘要】：建立大气细颗粒物(PM2.5)中16种多环芳烃(PAHs)的快速溶剂提取-直接进样-高效液相色谱测定方法。PM2.5经玻璃纤维滤膜收集,采样后的滤膜直接用乙腈经快速溶剂萃取仪提取,以乙腈和水作为流动相,提取液通过ZORBAX Eclipse PAH液相色谱柱分离,紫外串联荧光检测器检测。16种PAHs分离效果良好,在0.025~5.000μg/m L范围内线性相关系数r≥0.9998,方法加标回收率为78.3%~113.2%,相对标准偏差为0.5%~9.5%,检出限为0.007~0.062 ng/m~3。本方法操作简便、快速、准确、灵敏,适于PM2.5中16种PAHs的同时测定。
[Abstract]:A rapid solvent extraction-direct sampling-HPLC method for the determination of polycyclic aromatic hydrocarbons (PAHs) in atmospheric fine particulate matter (PM2.5) was established. PM2.5 was collected by glass fiber filter membrane. The sampled filter membrane was extracted directly by acetonitrile by a rapid solvent extractor. Acetonitrile and water were used as mobile phase, the extract was separated by ZORBAX Eclipse PAH liquid chromatography column, and 16 kinds of PAHs were detected by UV series fluorescence detector. In the range of 0.025 ~ 5.000 渭 g / mL, the linear correlation coefficient r 鈮，
