摘要：
The thermodynamic characteristics of complexation between ethylenediamine-N,N'-disuccinic acid (H4Y; EDDA) and Ho3+ ion were determined calorimetrically and potentiometrically at 298.15 K and ionic strengths of 0.1, 0.5, 1.0, and 1.5 (KNO3). The logK, ΔrG, ΔrH, and ΔrS values for the formation of HoY– and HOHY complexes were calculated at the studied and zero ionic strength values. The changes in thermodynamic parameters of the reactions are discussed.
