Supercritical Fluid Extraction of Sulfonylurea Herbicides in Soil Samples

The application of supercritical fluid extraction (SFE) with supercritical CO 2 to the analysis of 2 sulfonylurea herbicides in 4 soils is presented. Methanol and water are added to the soil samples as modifiers. After extraction, Chlorsulfuron and Metsulfuron methyl are measured by HPLC-UV at 220 n...
