摘　　要：建立了全自动固相萃取结合高效液相法测定水源水中的16种多环芳烃。从色谱条件、溶剂置换条件和萃取液浓缩方式等对水中16种PAHs的全自动固相萃取-液相色谱方法进行了优化研究。在0.05μg/mL^5.0μg/mL范围内测定标准系列溶液并绘制标准曲线,相关系数r>0.999;16种多环芳烃的仪器检出限为0.28ng/L^1.04ng/L;对水源水样品进行3个浓度水平0.05μg/mL、0.5μg/mL和5.0μg/mL,平均回收率在54.67%~96.05%之间;相对标准偏差(RSD)为3.1%~11.9%。方法自动化程度高,快速、灵敏、简单,适用于快速分析环境水样中的痕量多环芳烃。The chromatographic condition, solvent-displacement condition and extract-concentration means were optimized. Calibration curves were obtained in the concentration range of 0.05-5.0μg/mL with correlation coefficient R^2〉0. 999. The method quantification limits ranged from 0.28-1.04 ng/L. The average recoveries at 3 spiked levels （0.05, 0.5 and 5.0μg/mL） ranged from 54.67% to 96.05%, and the relative standard deviations（RSD）were in the range of 3.1%-11.9 %. The method is sensitive, repeatable, reliable and suitable for determination of polycyclic aromatic hydrocarbons in water.
