本文提出一个 PH 电位法测配合物生成常数的数据处理程序。程序中通过实验数据对理论计算值校正和三次样条函数插值,多项式拟合等方法,给出配合物各级 logk_(fi)的初步近似值,最后作连续迭代,求出更精确的 logk_(fi)值。该程序与作图法比较,相对误差在5％以内。 In this paper, we propose a data processing program for the determination of the complex formation constant by the PH potential method. In the program, preliminary approximation of logk_ (fi) at all levels of complex was given by experimental data correction of theoretical calculation and cubic spline interpolation and polynomial fitting. Finally, continuous iteration was performed to obtain more accurate logk_ (fi )value. The program compared with the mapping method, the relative error of less than 5%.
