Abstract: Sorption properties of the polyurethane foam treated by diethylammonium diethyldithiocarbamate have been utilized for enrichment and subsequent determination of Ag, Bi, Cd, Co, Cu, Mn, Ni, Pb, Sb, Sn, V, and Zn in drinking and river waters. Matrix elements as Al, Ca, Fe, Mg, and Si are not sorbed under the given conditions, the sorption of metal and transition elements is accomplished with a high separation yield and 1:100 or higher enrichment ratio. For final determination, the energy dispersive XRF spectrometry, AAS with flame atomization or AES-ICP method were applied.
