The influences of extraction parameters in the sample matrix were investigated. Under optimized experimental conditions, the detection limit (S/N=3), the quantification limit (S/N=10) and the enrichment factor of the proposed method for the target analyte were 0.96 μg/L, 3.20 μg/L and 54, respectively. The recoveries of target analyte spiked in real water samples were 87.4%~103%. The extraction performance of MAE-HS-LPME to the target analyte was also compared with liquid-liquid extraction (LLE). The results indicated that the developed method is simple, rapid, efficient, solvent-saving, highly selective and widely applicable. %K microwave-assisted extraction (MAE) %K headspace-liquid-phase microextraction (HS-LPME) %K high performance liquid chromatography (HPLC) %K dichlorvos %K environmental waters
