A rapid, efficient and accurate method was developed for the determination of 10 kinds of organophosphorus pesticides in tea by gas chromatography.Methods 10 kinds of organophosphorus pesticides were extracted by ultrasonic assisted with acetonitrile as solvent, and next purified by CARB/NH₂ SPE cartridges. At last, they were detected by gas chromatography-FPD. Results The linear range of the method was 0.05-1.0 mg/kg (r=0.999 63-0.999 86), relative recoveries for the spiked samples with 0.02-1.0 mg/kg of organophosphorus pesticides were ranged from 80.0% to 102.0%; the relative standard deviations (RSD, n=5) was 1.8%-5.8%, and the limits of detection (S/N=3) was 0.002-0.013 mg/kg.Conclusion The proposed gas chromatography-FPD method is convenient, quick and easy maneuverability, high separation effective and recovery rate.
