Abstract

An attempt has been adopted to synthesize a complex of uranium(IV) by using serine as a ligand. For the characterization of uranium(IV)-serine complex different analytical techniques such as semi-microanalysis, UV-visible spectroscopy, infrared spectroscopy, magnetic susceptibility measurements and cyclic voltammetry were employed. The metal to ligand ratio (M:L) in this complex was found to be 1:2, while coordinating sites in the complex was found to be amino and carboxyl groups of serine. The electrochemical studies demonstrate that uranium(IV) in this coordination complex oxidized quasi reversibly to uranium(V). There was no experimental evidence that supported the adsorption of either the reactant or product at the surface of the platinum electrode. Values of thermodynamic parameters indicate that the oxidation of uranium(IV) at platinum electrode is an endothermic and a non-spontaneous process.
