| Abstract: | A determination method of S-metolachlor residue was established by GC equipped with ECD detector. The sample was extracted by n-hexane, cleaned by florisil-SPE column. The average recoveries of the method ranged from 84.47%-105.92% , and the coefficient of variation was 0.87%-7.81%. The lowest detectable concentration of soil, plant and bean were 0.01 mg/kg, respectively. The sensitivity, accuracy and precision of this method were satisfied for pesticide residue analysis. |
