Abstract
|
|
|
|
The simultaneous analytical method for 37 residual pesticides was developed by a gas chromatography with ^63Ni electron capture detector. Pesticides added in soybean sample were extracted with 70% acetone in water and methylene chloride in order, and then cleaned up via open-column apparatus packed with florisil and alumina N. The Ultra-2 fused capillary column was used to separate the products. The resolution between the last isomeric peak of cypermethrin (56.398 min) and the first isomeric peak of flucythrinate (56.421 min) was not satisfactory and the last isomeric peak of fenvalerate (58.783 min) and the first isomeric peak of fluvalinate (58.835 min) was overlapped. Except for α-BHC, dichlofluanid, captan, and captafol, most recoveries were showed over 70%.
