摘要:
Mixed-ligand complexation of GdEdta(-) with glycinate, L-glutamate, DL-aspartate, iminodiacetate, and nitrilotriacetate anions in aqueous solutions at 298.15 K and the ionic strength I = 0.5 (KNO(3)) was studied. The thermodynamic parameters (logK, Delta (r) G, Delta (r) H, Delta (r) S) of these reactions were determined from calorimetric and pH-metric data. The most probable way of coordination of the amino acids in the heteroleptic complexes is discussed.
