校正计算法测定混合酸中各组分浓度

Determination of Components in Mixed Acids by Multivariate Calibration Method

本文提出混合酸分析的新方法,该法利用已知混合酸的电位滴定数据建立多元线性回归数学模型,应用该模型对未知混合酸中各组份进行浓度测定,整个校正及测定过程中无需知道酸的离解常数。

A new method for the determination of components in mixed acids is presented. In this method, a model is developed from samples of known composition (calibration set), and is then used to predict unknown(test samples). The potentiometric data processing is carried out by using multiple linear regression. Four demonstrations of this method for the determination of mixed acids, such as two binary and two ternary, are given and the results are satisfactory.
