本文提出了混合酸中多组分同时测定的新方法。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,用该模型对未知混合酸中各组分进行浓度测定。方法简便、快速、实用。
This paper presents a new method for the simultaneous determination of multiple components in mixed acids. The method uses the potentiometric titration data of known mixed acids to establish the mathematical model of multiple linear regression, and uses the model to determine the concentration of each component in unknown mixed acid. The method is simple, fast and practical.
