摘要
本文以主成份分析法对混合酸进行定量测定,该法能充分提取滴定数据中的有效信息,因此可获较满意的结果。
A mathematical method for the determination of mixed acids is presented. In this method, a principal component regression model is obtained from a set of mixed acids of known composition and is then used for predict the unknowns. This method has the advantage to obtain more useful informations in potential data matrix〔V〕than the traditional ones. This method is applied to three complex mixed acid systems and the results are satisfactory.
