因子分析─电位滴定法同时测定混合酸中各组分酸的研究

Simultaneous Determination of Multicomponents in Mixed Acids by Using Target Factor Analysis-Potentiometric Titration

采用电位滴定法同时测定电离常数相近的二组分及三组分混合酸中各组分酸的含量，建立了因子分析─电位滴定法同时测定多组分混合酸的数学模型，比较了两种多元线性回归及目标因子分析法用于同一体系的优缺点，结果表明目标因子分析法最为适宜．用人工合成样验证，获得满意结果．

A new method of simulatneously determining multicomponents in mixed acids that the pKa are very near was established and a mathematical mode of target factor analysis-potentiometric titration was set up. The comparison between the method and two other kinds of multiple linear regnssion with the same systems for the simultaneous determination of the two componentS and three components mixed acids was carried out.of the three chemometric methods, target factor analysis is more suitable for the mixtures.The simple and rapid method was satisfactorily applied to the analysis of synthetic samples
