摘要：本文利用简便的滴定过程模型,确立了微机模拟处理实验数据,方便、准确地求解络合滴定等当点的方法。设计了最佳实验条件模拟估计程序。该法测定Zn^(2+),Pb^(2+),Cu^(2+),Fe^(3+)结果的相对误差Δ<1％。pH=6-7时,测定Ca^(2+)的相对误差为-1.61％;σ<0.001mmol,(N=5)。
On the basis of our mathematic models of the titration, the method of finding the equivalence point conveniently with the help of personal computer is presented. The program which can estimate the experimental conditions is created in order to omit the trial and error. The determinations of Zn^(2+), Pb^(2+), Cu^(2+), Fe^(2+) and Ca^(2+) are carried out potentiometrically with the aid of the glass electrode. The relative deviations are between±1% except -1.61% for Ca^(2+) which is titrated at pH=6～7. The standard errors are less than 0.001 (retool) (N=5).
