摘  要:
[Objective]The aim aim was to develop a fast method for determination of 10 kinds of organochlorine pesticide residues including residues of BHCs and DDTs in source water and drinking water.[Method]With optimized experimental conditions,10 kinds of organochlorine pesticide residues including residues of BHCs and DDTs in source water and drinking water in Nanchang city were determined by gas chromatography with liquid-liquid extraction,clean-up with concentrated sulfuric acid,OV-17 capillary chromatic pillar and ECD.[Result]The linear range of the method was 0.001 ~0.01 μg/ml,with recoveries in the range of 90.3%-109.8%,and relative standard deviation in the range of 2.5% 6.9%.[Conclusion]The method was fast,economical,and applicable to the determination of organochlorine pesticide residues in source water and drinking water.
