摘要
本文详细地分析了用pH-电位法测定 K 元(K=1,2,3,4…)配合物稳定常数通用程序的数学基础,应用该程序,只需向微机输入不同的简单整数即可表征不同的化学模型,使计算程序具有很好的通用性,为复杂配位化学体系的稳定性研究提供了强有力的数据处理手段。
A general mathematical model is described in detail for the evaluation of stability con-stants of binary and polynary complexes for multicomponent system from potentiometricdata.Stability constants must have indices m,l,l and h which define the speciesM_mL_l'L'_l',H_h.The model defined by the set of parameters can readily be changed so thatthe user can see how a new model affects the species distribution.Matrix algebra is ideallyapplicable to the treatment of potentiometric data for multicomponent system.The paperpresents a new application of this mathematical technique.
