摘要：
Heat effects of the reactions of formation of complexes of the composition CoTrp+ and CoTrp2 were measured by direct calorimetry. Analysis of the effect of the ion force of the solution (0.25, 0.50, and 0.75 M KNO3) on the heat effects of the processes of complex formation in the D,L-triptophan-Co(II) system at different temperatures (288.15, 298.15, and 308.15 K) was carried out. Standard thermodynamic characteristics of the reactions of formation of complexes in the system under study were evaluated.
