建立了无溶剂固相微萃取（SPME）测定废水中多环芳烃（PAHs）的新方法。多环芳烃用100 μm聚二甲基硅氧烷（PDMS）纤维提取，在40 μl乙腈中解吸，用液相色谱和荧光检测器测定。在给定条件下（从5 ml样品中提取，提取时间1 h），这种非常简单的方法的检测限在1-6 ng l-1范围内。浓度水平为0.8 μg l− 1时的标准偏差（n=6）在1.8%至14.4%之间。该方法用于污染水样中多环芳烃的测定。
A new method for the determination of polycyclic aromatic hydrocarbons (PAHs) in waste water using solvent-free solid-phase microextraction (SPME) is described. The PAHs are extracted with a 100 μm polydimethylsiloxane (PDMS) fiber, desorbed in 40 μl acetonitrile and measured with LC and fluorescence detection. The detection limits of this very simple method under the given conditions (extraction from 5 ml sample, extraction time 1 h) are in the range of 1–6 ng l−1. The standard deviations (n=6) at a concentration level of 0.8 μg l−1are between 1.8 and 14.4%. The procedure was used for the determination of PAHs in contaminated water samples.
