Abstract: |
A simple, rapid and effective method, the dispersive liquid-liquid microextraction with high-performance liquid chromatography (DLLME-HPLC), has been developed for the extraction and determination of nonylphenol in environmental water samples. The factors relevant to the microextraction efficiency, such as the type and volume of dispersion agent and extraction solvents, the extraction time and so on were investigated and optimized. Under the optimized extraction conditions, the linear response of this method was in the range of 5～1000μg/L (r = 0.9995), the relative standard deviation (RSD) for 80μg/ L of nonylphenol was 6.8% (n = 6). The detection limit was 0.20μg/L. The developed method was successfully applied to the determination of trace amount of nonylphenol in three kinds of real environmental water samples with spiked recoveries in the range of 74.3%～106.7% (n = 5). The results showed that this method is suitable for the determination of trace amount of nonylphenol in environmental water samples.
