【Abstract】 The analytical methods of pretilachlor in environmental wastewater are studied in this paper. Gas chromatography and capillary columns are used to separate pretilachlor and both ECD and NPD are used to detect it. The good separate efficiency and high sensitivities can be got. The lowest detection limit can reach 0.01mg/L. We can obtain reliable analytical results by using double columns and double detects in analysis, which can avoid the mistaken results because of the incompletable separation.更多还原
