摘要：

The thermodynamic parameters (logK, Delta (r) G (0), Delta (r) H, and Delta (r) S) for mixed-ligand complexation of LnEdta(-) (Ln(3+) = La3+, Ce3+, Pr3+, Nd3+, Sm3+, Gd3+) with iminodiacetate and nitrilotriacetate ions in aqueous solution at 298.15 K and ionic strength I = 0.5 (KNO3) were determined by calorimetry and pH-metry. The variation of the thermodynamic parameters of the reactions over the lanthanide series was discussed.
