Abstract An analytical method based on the use of a liquid chromatograph equipped with a UV detector was developed for the determination of acifluorfen In soil and water. Acifluorfen was extracted from soil In methanol-0.10N NaOH (80 + 20 v/ v) and from water by partition with dlchloromethane. Solvent partitioning and solid-phase extraction were used to separate acifluorfen from major Interfering sample components. Average recoveries from soil at 1, 0.1, and 0.01 ppm fortification levels were 95.1 ± 3.4,92.6 ± 2.9, and 73.9 ± 3.0%, respectively. Recoveries from water spiked at levels from 0.01 to 1 ppm averaged 96.5 ± 5.4%. Method limits of detection were 0.006 ppm in soil and 0.003 ppm In water.
