ABSTRACT
Objective To establish a gas chromatography method for the determination of 50 organochlorine and pyrethroid pesticides residues in Zigyphussp. Methods The organochlorine and pyrethroid pesticides were extracted from Zigyphussp with solvents of acetonitrile (1%acetic acid) by accelerated solvent extraction (ASE) for 5 min at 100℃. Then the extracts were cleaned up by alumina neutral-florisil column and eluted by mixed solvents of ethyl acetate and hexane (15∶85, V/V). The extract was separated by HP-5 and DB1701 capillary dual-column and detected by electron-capture detector. Results The average recoveries and RSD ranged from 71.4% to 110.9%and 1.2% to 14.1% respectively, at three spiked mixed organochlorine and pyrethroid levels. Conclusion The method has good separation and repeatability, and can be used in determination of organochlorine and pyrethroid pesticide residues in Zigyphussp.
