Chelating resin loaded with 5-sulfosalicylic acid, Poly[N-chloranilN ,N,N',N'-tetramethylethylenediammonium di-sulfosalicylate], was obtained by an ion-exchange reaction withN ,N,N',N'-tetramethylethylenediamine-chloranil copolymer as matrix. A useful chromatographic packing is prepared by immobilizing this chelating resin on silica gel. A detail analytical characterization of this silica-immobilized sorbent was carried out and optimum and selective sorption conditions for some heavy metals under static and dynamic conditions were established. The maximum absorption capacity was found to be 3.95 μmol of metal ions per gram of the sorbent at their respective optimum pH (optimum pH values for selective metal ions are: Cd 2 + , 3.2; Cu 2 + , 4.5; Fe 3 + , 5.0; Co 2 + , 6.9). The typical flow rates of 5 ml/min for Cu 2 + , Co 2 + and Fe 3 + , and 3 ml/min for Cd 2 + were found suitable for selective and quantitative separations of these metals from the multicomponent mixtures of heavy metals present in the water samples. After separation of traces of metals on the sorbent and subsequent desorption with 1 M nitric acid, the metal ions were determined in the eluent by employing differential pulse anodic stripping voltammetry.
