| 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 0.67~ 1.50 ng/mL with linear ranges of 0.67~600 ng/mL and correlation coefficients of 0.9994~0.9999. 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. |
