THE THERMODYNAMIC PARAMETERS OF FORMATION OF LANTHANIDE SQUARATE COMPLEXES

Abstract

The thermodynamic parameters of complexation of the lanthanide ions by squarate anions have been measured by potentiometric and calorimetric titrations. The design and operation of the calorimeter is described as it has some unique features. The complexes are weaker than analogous complexes with other hydroxy-keto ligands due to a more endothermic enthalpy of complexation.
