| Abstract: | A method was developed for determination of multi-organophosphorous pesticide residues in sesame seeds by capillary gas chromatography with FPD. The sesame seeds were treated with acetonitrile and acetone(10 1),then the analyts were extracted by ultrasonication. The extracts were purified on the activated florisil and neutral aluminum oxide column. The average recovery was from 82.1% to 109.7%. |
