Abstract

Potentiometric and calorimetric investigations of uranyl(VI) complexes with glycylglycine and glutathione have been carried out in 1.0 mol dm −3 aqueous solution of sodium perchlorate at 25.0 ° C. The experimental data of the urany(VI)-glycylglycine system can be explained by assuming the formation of three successive entropy-stabilized mononuclear complexes, whereas for the uranyl(VI)-glutathione system, a 1:1 complex only is present, due to the low pH values at which precipitation of solid compounds occurs. The values obtained for the stability constants and for the enthalpy and entropy changes are discussed in comparison with parent complexes involving some amino acid ligands.
