| Abstract: | In this paper, the potentiometric titrating data in multicomponent analysis were processed respectively by CPV matrix method and principal component analysis (PCA).The components of phosphoric acid and phosphorous acid in phosphorous materials were determined simultaneously. The experimental results show that the accuracy of PCA is better that CPV matrix method. |
