| Abstract: | Objective:To determine 9 organochlorine pesticides(OCPs) in soil by gas chromatography with electron capture detector.Methods:Samples were extracted with organic solvent using supersonic fluid extraction.The extracts were cleaned up by concentrated H2 SO4.The column was OV-1701(30m×0.32 mm×0.32μm).Results:The average recoveries were 84.7%～117.1% and RSD were 3.36%～7.65%.The OCPs of the soil are lower than environmental quality standard for soils(GB/T 14550-93).Conclusions:This method is rapid,simple and accurate.It can be used to determine organochlorine pesticides in soils. |
