National Research Center for Geoanalysis Beijing China 2. Oil & Gas Technology Research Institute of Ghangqing Oilfield Company Xi'an China 3. Civil and Environmental Engineering College University of Science and Technology Beijing China Abstract A method for the determination of organophosphate pesticides OPPs in soil samples by accelerated solvent extraction-gas chromatography ASE-GC was developed. Through the extraction by ASE clean-up with Carb column 13 OPPs in soil samples were separated and determined by Rtx-OPP2 wide bore capillary-gas chromatography with electron capture detector. The detection limits of the method for OPPs were ~ ng /ml with linear ranges of ~ 600 ng /ml and correlation coefficients of ~ The average recoveries for 13 OPPs in simulated soil samples and real soil samples were 54. 3% ~ 106% and 60. 7% ~ 133% with precision of 2. 2% ~ 9. 9% RSD n = 5. The method provides the advantages of high sensitivity high reliability convenience and is suitable for analysis of OPPs in soil samples.
