Abstract:Solid phase extraction and capillary gas chromatography were applied to the determination of four pyrethroid pesticide residues in small white almond samples. The results showed that four kinds of pyrethroid pesticides were separated from each other, and the liner range of standard curve was broad. The minimum detection limit, the relative standard deviation, and the recovery rates of the method were lower than 0.6 g/L (0.214 g/L~0.594 g/L), less than 10% (2.48%~8.05%), and between 76.46%-102.96%, respectively. The method was simple, rapid, economical and had high sensitivity, accuracy and precision. It was suitable for the determination of pyrethroid pesticide residues in small white almond samples as well as in other fruits.
