Abstract: The preconcentration of metal on a polyurethane foam modified by dithizone was used for the determination of the trace amounts of Pb in waters and soils. The optimum conditions for the sorption and the desorption were found. The detection limit was found out for the determination of Pb at 1.4 μg dm^-3.
