| Abstract: | The residues of organochlorine pesticides in surface water were determined by capillary gas chromatography.The organochlorine pesticide residues were extracted from water with Acetone,cleaned up by concentrated sulfuric acid,separated by capillary column SPBtm-5(30m×0.32 mm×0.25 μm) and detected by GC-ECD.The other conditions are as follows : carrier gas N2(99.999%,1.0 ml/min);splitless inlet;injector temperature 235℃;detector temperature 300℃;columntemperature program : 60℃(hold 0.5 min),rate of 20℃/min to 120℃ then rate of 4℃/min to 265℃.The average recoveries were within 90.8%～116.0%,and RSD2.11%～14.2%. |
