| 中文摘要: |
| 采用C18固相膜萃取对地下水中15种多环芳烃进行富集净化，以二氯甲烷作洗脱溶剂，高效液相色谱法，荧光检测器测定。对萃取、浓缩和色谱条件进行优化，在1.00 μg/L～40.0 μg/L范围内测定标准系列溶液并绘制标准曲线，相关系数R2>0.999；15种多环芳烃的仪器检出限为0.4 ng/L～3.0 ng/L；对地下水样品加标，平均回收率在75.7%～96.7%之间；标准溶液平行测定7次的RSD为3.1%～11.9%。 |

| High performance liquid chromatography equipped with fluorescence detector was applied to the determination of 15 polycyclic aromatic hydrocarbons (PAHs)in groundwater. The water samples were enriched and purified by C18 solid phase membrane with methylene chloride as elution solvent.Solid phase extraction condition and liquid chromatography condition were optimized. Calibration curves were obtained at concentration range of 1.00 μg/L～40.0 μg/L with correlation coefficient R2>0.999. The method quantification limits ranged from 0.4 ng/L～3.0 ng/L.The spiked recoveries of groundwater were from 75.7%～96.7%. The relative standard deviations were 3.1%～11.9% when 7 samples with known concentrations were determined. |
