| 摘要: 本文用分光光度法确定了25℃下配阳离子Cu(SCN)+在NaNO3-叔丁醇-水介质中的稳定常数。混合溶剂中叔丁醇组成为0，5，10，15，20和25 wt%，离子强度范围为0.2～3.0 mole·dm-3，溶液的pH=1.5～1.6。基于Pitzer理论用最小二乘多项式逼近法，确定了混合溶剂中配合物热力学稳定常数。讨论了配位反应的一级介质效应。 |

| Abstract: The stability constants of Cu(SCN)+ ion in the NaNO3-tert-Butyl alcohol-H2O medium have been determined by spectrophotometric measurements at 25℃ for 0, 5, 10, 15, 20 and 25 wt% to tert-butyl alcohol in mixed solvent. The total ionic strengths of the solution are 0.2～3.0 mole·dm-3, and pH=1.5～1.6. On the basis of Pitzer′s theory, a method of determining thermodynamic stability constants of coordination compounds in mixed solvents by polynomial approximation has been proposed. The primary medium effect of coordination reaction have been discussed. |
