Abstract A method Is described for the determination of residues of isoxaben and its principal soil metabolite In soil and soil-turf samples. Both compounds are extracted from samples by refluxing with methanol-water. An aliquot of the extract Is partitioned Into dichloromethane and purified by alumina column chromatography. Separate fractions containing isoxaben and metabolite are collected and subjected to liquid chromatography at conditions that are optimized for each compound. The detection limit for both compounds is 0.005 ppm. Residue identities are confirmed by chromatography on a different LC system.
