摘要: 在同時考慮絡合劑離解平衡、金屬離子水解平衡及絡合平衡間的相互影響的情況下,分析了各離子分布系數理論計算的數學方程式,利用計算機對金屬離子加絡劑體系中各離子分布系數的計算進行解析,給出了最簡便優化的運算方法及程序框圖,詳細討論了多元酸絡合劑體系中單絡合劑及雙絡合劑的情況,并進一步將結果推廣到更普遍的情況,對化學鍍鎳中常用絡合劑體系的離子分布系數進行了計算。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.
