%X A simple, rapid and effective method, the dispersive liquid-liquid microextraction coupled with high performance liquid chromatography-fluorescence detection (DLLME-HPLC-FLD), has been developed for the extraction and determination of polynuclear aromatic hydro-carbons (PAHs) in environmental water samples. The factors relevant to the microextraction efficiency, such as type and volume of dispersion agent and extraction solvents and the extrac-tion time were investigated and optimized. Under the optimized extraction conditions, the relia-bility of the proposed method was evaluated. The linear response of this method was in the range of 0. 01-10 μg/L (r≥0.991 3), the relative standard deviations (RSDs) of peak area for 0.05 μg/L PAHs were in the range of 2.3%-4. 7% (n = 6). At room temperature, the method exhibited excellent enrichment factors and good recoveries, 674-1 032 and 67. 4%-103. 2% respectively. The detection limits (S/N = 3) were in the range of 0. 000 3-0. 002 μg/L. The developed method was applied to the determination of 15 PAHs in the water from Aojiang river, the average recoveries were 79. 5%-92. 3% with RSD of 4. 3%-6. 7% (n=5). The developed method is suitable for the analysis of trace PAHs in environmental water samples.
