Investigations of solid electrodes modified with 2,2'-bipyridyl in a polyaniline matrix were carried out. Interactions between lead and copper atoms in the solid solution change the potentials and currents of the peaks corresponding to anodic stripping. These changes cause serious errors in quantitative determination of the metals by anodic stripping voltammetry (ASV). 2'2-bipyridyl forms a stable complex with copper ions and the accuracy of lead determination is significantly improved as well. The molecules of 2'2-bipyridyl were immobilized on the electrode surface in a polyaniline film obtained during electrochemical oxidation from the solution containing aniline, the ligand, and sulphuric acid. The results discussed below enable to determine the optimum conditions for preparation of the modified electrode.
