| Abstract: | A method was developed for determining chlorsulfuron residues in soil by gas chromatography. Soil samples were treated with 0. 15 mol/L sodium bicarbonate, and then extracted with dichloromethane. The extract was hydrolyzed into p-chlorobenzene sulfon-amide in boiling water, then also extracted with dichloromethame. The dichloromethane extracts after clean-up on Florisil column were concentrated for gas chromatographic analysis. The detection limit was 0. 3 ng/g and recovery of chlorsulfuron in soil was 78. 5%-90. 8%. |
