Open publisher page 0 citations

Abstract

A method for the extraction,clean\|up and determination of cypermethrin,fenvalerate and deltamethrin residues in tomato jam was developed.The pesticides determination was performed by electron capture gas chromatography with a OV 17 capillary column.Purification of the pesticides was performed by a column packed with florisil.The recoveries of this method ranged from 82.6%- 88.1% ,and detection limit is 0.05mg/kg.
