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.
