Abstract
The ion-pair formation between the metal complex with 4-(4'-nitropheny lazo)-1-naphthol and cetyl-trimethylammonium bromide and its sorption on silica gel form the basis for preconcentration of cadmium and lead, which are subsequently determined on-line by flame AAS. The method wa s applied to the quantitation of cadmium and lead in potable and surfa ce waters, with limits of determination (10s) of 0.5 and 2 mu g l(-1), respectively.
