Abstract
The polymer-metal ion interactions were studied by cyclic voltammetry. Thes e were carried out with poly(acrylic acid)-Cu(II) and poly(vinylsulfonic ac id)-Cu(II) systems at different pH. At low pH, the polymer was adsorbed on the electrode surface increasing the irreversibility of the Cu2+/Cu(s) redo x system. At pH 2.7, it was possible to demonstrate that the interaction be tween Cu(II) and poly(vinylsulfonic acid) is basically electrostatic and wi th poly(acrylic acid) a complex formation also exists.
