| Abstract: | A GC-ECD method for the determination of dimethachlon pesticides residues in cigarette filter samples was established and the optimum pretreatment conditions were discussed.The samples were extracted with methanol and rapid qualitative and quantitative analyses were carried out by gas chromatography electron capture detection with a DM-1701 capillary column.Results show that the detection limit is 0.0182 mg/kg,the average recoveries of standard addition ranges from 81.5% to 93.7%,and the relative standard d... |
