Abstract

Abstract

This paper proposed a determination method for 8 organophosphorus pesticides residues of dichlorvos, methamidophos, acephate, phorate, omethoate, dimethoate, parathionmethyl and chlorpyriphos in leek. The 8 organophosphorus pesticides were separated from each other through DB-608 capillary column and determined by flame photometric detector, and the recoveries ranged 70%~119%. The lowest determination concentrations of the 8 organophosphorus pesticides are 0.01~0.02 μg·mL^-1 This method is rapid and sensitive, and meets the demands of actual application.
