Abstract : Formation of complexes of type ML and ML2, where M=UO2(II) and L = malic acid, lactic acid, salicylic acid or mandelic acid have been studied by using modified form Bjerrum method in aqueous media at different temperatures and ionic strengths. The resulting formation constants, logβ for UO2(II)—Hydroxy acid complexes have been calculated by considering BESTFIT model and using Fortran IV program BEST based on least square calculations. Thermodynamic parameters are also evaluated, negative ∆G0, ∆H0 and ∆S0 values indicate that complex formation is favourable at 303.15K, 313.15K and 323.15K. Using SPEPLOT Fortran IV program, species diffusion curves of complexes are plotted to fantasize about the presence of variegated species in equilibrium. To understand more about this equilibrium, the stability of these complexes is studied in presence of systemic errors which are added as [acid], [alkali], [metal], [ligand] and carbon dioxide concentration changes.
