Resumo: | A method for simultaneous determination of nine sulfonylurea herbicides in water and soil samples with solvent demulsification-dispersive liquid-liquid microextraction based on solidification of floating organic drop coupled with high perfomence liquid chromatography was established. 120 µL of 1-dodecanol as extractant and 400 µL of methanol as dispersing reagent were injected into the sample solution adjusted to pH 2.0 to extract the target compounds for high performance liquid chromatography (HPLC) analysis. The detection limits were 0.24-0.81 µg L-1 for water samples and 2.42-8.12 µg kg-1 for soil samples, and the quantification limits were 0.79-2.69 µg L-1 for water samples and 8.06-27.04 µg kg-1 for soil samples respectively. The average recoveries were 78.9-104.8% with the relative standard derivations (RSDs) of 2.73-10.4% for water samples, and 75.5-107% with the RSDs of 5.66-12.4% for soil samples. The method had the advantages of little consumption of organic solvent, low cost and high enrichment factors. |
