Determination of Organophosphorus Pesticide Residues in Tobacco

Abstract

Abstract

Tobacco sample was extracted with acetone, the resultant extract was cleaned by liquid-liquid partition with ethyl acetate and cyclohexane, and then purified by GPC.The residues of ten organophosphorus pesticides were determined by GC/FPD.The average recoveries of the method were(72.8%-108.1%) and RSD was less than 10%.
