Abstract
The dimethyl phthalate,diethyl phthalate,dibutyl phthalate,benzyl butyl phthalate,di-2-ethyl hexyl phthalate and dioctylphthalate in the water were determined by dispersive liquid-liquid microextraction/gas chromatography with extraction solvent of carbon tetrachloride and dispersive solvent of acetonitrile.The optimized tests produced the following results: a good linearity in range from 1.00 μg/L to 100 μg/L of the six PAEs;detection limits of the method 0.18 μg/L～2.5 μg/L;RSD of standard solution≤6.1%;spiked recoveries of water samples from BaiYang Lake 70.9%～119%.
