“…A number of 5-(pyridylmethylidene)-2-thiohydantoins (ligand similar to that described by us) complexes with heavy metals such as Cu 2+ , Ni 2+ , Co 2+ , revealed a double coordination of the metal by sulfur and 3-nitrogen atoms [18]. Such complexes were observed also at other similar compounds, especially to p-dimethylbenzylidenerhodanin, which is widely used for the absorption of toxic metals in solutions with very low concentrations or for their dosage, for example Ag + ion [19], Au 3+ , Hg 2+ ions [20] or other thiophilic ions [21].…”

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+.
