✦ Synopsis

Polypyrrole modified platinum electrodes bearing anionic bathophenanthroline disulfonate were prepared by electrochemical oxidation of pyrrole in the presence of these species. The modified electrodes were applied in the electroanalysis of copper species. The interactions between the incorporated ligands and the copper ions were studied by the impedance technique. Results suggested that the impedance behavior reflected the concentration dependence of the electrochemical response.
