Electroactive properties of a new azulene thioxo-imidazolidin-4-one ligand for modified electrodes

Sa？etak The electrochemical characterization of a new synthesized azulene compound (Z)-5-((5-isopropyl-3,8-dimethylazulen-1-yl)methylene)-2-thioxoimidazolidin-4-one (L) using cyclic voltammetry, differential pulse voltammetry and rotating disk electrode is presented. Chemically modified electrodes were obtained by successive scanning or by controlled potential electrolysis using different electrode potentials or charges. The new modified electrodes were tested in solutions containing different concentrations of the following heavy metals: cadmium, lead, mercury and copper. A good analytical response was obtained for Pb2+
