Abstract: A method for rapid determination of seven common Organo-phosphorus pesticides in tea sample by gaschromatography was purposed. The pesticides were analyzed by GC(HP6890) with DB-5 capillary column and FPD detector.The results showed that the recoveries of these seven common pesticides were between 76.4%~103.8%, the coefficients ofvariation between 6.3%~10.6% and the LOD between 0.0034~0.0675μg/g.
