Abstract

The redox behavior of silver ion [Ag(I)] is studied at carbon paste electrodes (CPE) in presence of the macrocyclic ligand 2,5,8-trithia[9]-m-cyclophane (TTCP) in ethanol. The formation of a Ag(I) complex of the TTCP is concluded from the appearance of two oxidation peaks and two corresponding reduction peaks at the CPE. Potemiostatic pretreatment (at potentials in the range from -0.4 V to +0.25 V) leads to the adsorption of the ligand as well as the deposition of Ag(0) at the electrode surface, which reacts then to the Ag(I) complex during the anodic cycle. The results indicate that TTCP can be used as electrode modifier for the immobilization of silver at electrode surfaces.
