The separation and determination of phthalate esters in water by micellar electrokinetic capillary chromatography (MECC) have been studied. The peak area is used for quantitative analysis. The results show the correlation between the peak area and concentration is good，the correlation coefficient is higher than 0.999. The relative standard deviation is within 0.98%一6.16%. Micellar electrokinetic capillary chromatography is used for quantitative determination of the contents of butyl benzyl phthalate in plastic industry wastewater. The recovery range for the spiked samples is from 104.8% to 108.9%.
