| Abstract: | In this paper a small volume liquid-liquid extraction(SVLLE) method combined with gas chromatography coupled with dual-tower and dual-column for the rapid determination of organochlorine pesticide in surface water is developed.The method is simple and fast.Only 1.5 mL of extraction solvent is used.The enrichment factor can be 270~470.The recovery rate is in the range of 92.7%~102% with RSD in the range of 2.3%~6.5%,and the detection limit in the range of 0.02~0.04μg/L. |
