Resumo

Enthalpies of complexation of diglycine (HL^±) with Pr³⁺ and Sm³⁺ ions at 303.15 K and I = 0.5 (KNO₃) have been determined by means of calorimetry. The thermodynamic parameters of the formation of diglycine complexes with Pr³⁺ and Sm³⁺ ions have been calculated at different molar ratios between metal and the ligand.
