因子分析法在混合酸各组分浓度测定中的应用

Determination of Component Concentrations in Mixtures of Acids by Factor Analysis

首次建立了在定pH滴定条件下,混合酸中各组分浓度与量测值滴定体积和溶液pH之间关系的数学模型。采用因子分析法求解,可确定被测体系中组分数和各组分含量,适用于多组分多样品的同时测定。

A general expression of the relation among the component concentration, the volume of titrant and the solution pH in mixtures of several acids is derived under the fixed pH titration condition. The expression is well suited to solve this equation by multivariate analysis methods.In this paper a mixed acid analysis is investigated by factor analysis. Several mixed systems were testified with satisfaction, the method is more reliable and simple.
