摘要：

The formation of mixed ligand complexes in HgEdta(2-)-L systems (L = Asp(2-), Glu(2-), Ida(2-), Nta(3-), and Edta(4-)) is studied via calorimetry, pH-metry, and NMR spectroscopy. The thermodynamic parameters (logK, (r)G degrees, H-r, S-r) of complexation reactions are determined at T = 298.15 K and ionic strength I = 0.5(KNO3). The most plausible mechanism of ligand coordination within a mixed-ligand complex is discussed.
