Abstract
A new solid-phase extraction procedure using a polyurethane foam plug column has been tested for the preconcentration of traces of carbaryl (50-400 ppb) present in water. The plug was Soxhlet extracted with chl oroform, the solvent was evaporated, the residue was dissolved in meth anol, and the carbaryl was determined spectrophotometrically. Recovery was 73-80, 82-88, 91-97, and 94-98% from deep-well water, river water , rain water, and distilled water, respectively. (C) 1995 Academic Pre ss, Inc.
