| Abstract: | Using capillary gas chromatography method and solid phase extraction sample preparation to determine chlorothalonil residues in vegetables. With acetonitrile as solvent extraction,solid-phase extraction for sample pretreatment,gas chromatograph （ECD detector）as detection,the recovery of chlorothalonil was from 94.1%to 102.2%,the coefficient of variation was less than 2.78%. |
