| Abstract: | The gas chromatograph-electron capture detector was established to test the residual of organochlorine and pyrethroid pesticides in Duyun Maojian Tea. Using RTX-1 （30 m×0. 25 mm×0. 25 μm） capillary column and SPE, this method was with recovery of 94. 69% ~103. 90%. By using the method to test pesticide residue in Duyun Maojian Tea, which had the features of small usage amount of solvent, good purification effects, easy to handle, fastness, sensitiveness, reliability, etc. |
