| Abstract: | A method for determination of 7 carbamate pesticides residue （including aldicarb sulfoxide, aldicarb sulfone, methomyl, 3-hydroxyc- arbofuran, aldicarb, carbofuran, carbaryl）in strawberry by high performance liquid chromatography was investigated.The seven pesticides could be well separated within 30 min in a Cis column after being extracted with acetonitrile and cleaned up by solid-phase aminopropyl column.The pesticides were detected with FLD detector.As a spiked level was 0.3 mg/kg,the recovery of the method for the pesticides were 86.7%-106.5% ,the correlation coefficient ranged from 0.999 174 to 0.999 987, the detection limits were 0.01-0.02 mg/kg.The method is quick, sensitive and easy in operation. |
