| 摘 要： | 在同时考虑络合剂离解平衡，金属离子水解平衡及络合平衡间的相互影响的情况下，分析了各离子分布系数理论计算的数学方程式，利用计算机对金属离子加络合物体系中各离子分布系数的计算进行解析，给出了最简便优化的运算方法及程序框图。详细讨论了多元酸络合剂体系中单络合及双络合剂的情况，并进一步将结果推广到更普遍的情况，对化学镀镍中常用络合剂体系的离子分布系数进行了计算。

| Abstract: | Equations of theoretical calculating distribution coefficients of ions in complex system were analyzed, considering dissociations of the complexants, hydrolizations of metal ions and interactions between complexes at the same time. An optimum and simple calcula- tion method by computer and its program frame were put forward. Distributions of ions in two common complex systems of electroless plating of nickel were extracted. |
