Thermochemistry of Complex Formation of Ni~(2+)with Glycyl-L-Asparagine in Aqueous Solutions

摘要

The heats of formation of complexes in the glycyl-L-asparagine-Ni~(2+)system were determined by calorimetry in an aqueous solution at ionic strengths of 0.5,1.0,and 1.5(KNO_3)and a temperature of 298.15 K.The thermodynamic characteristics of the formation of nickel complexes with dipeptide were determined.The influence of the ligand structure on the complexation thermodynamics in solutions was discussed.
