Abstract

A procedure is developed for the determination of Cd, Cu, Mo, Pb, Te and Ni in natural and spiked water by Atomic Absorption Spectroscopy (AAS) after preconcentration on a coniine dithiocarbamate supported by polyurethane. The sorbed elements are subsequently eluted with 5 mol L-1 HNO3 and the acid eluates are analysed by AAS. A 20 mL syringe served as a chromatographic preconcentration column. The sorption recoveries of elements were higher in the order of 99%. The method is also applied successfully for the determination of Cu, Cd, Mo, Pb, Te and Ni in natural and spiked water samples.
