Abstract

A method for the determination of chlorothalonil,triadimefon,bifenthrin,fenpropathrin,lambda-cyhalothrin,permethrin,cypermethrin,fenvalerate and deltamethrin in rice by using GC/μ-ECD was developed.The 9 pesticide residues in rice were separated from each other through DB-1701 in 24 min.It was then analyzed by GC/μ-ECD using the external standard method.Under above conditions,the average recoveries of various amounts of spiked(0.05-0.50 mg/kg) in rice were ranged from 69.87 to 135.51%.The detection limit for the 9 kinds of pesticide pesticides was in the range of 0.000 04-0.009 mg/kg and the RSD from 1.83 to 18.68%.
