| Abstract: | A new method for the simultaneous determinatiuon or phosphoric acid and phosphorous acid is presented. In this method, a mathemahcal mode of multivariate linear regression is establised by using potentiometric titration data of known mixed acids. The method is used to determine concentrations of phosphoric acid and phosporous acid respectively in the unknown mixed acids, and the results are satisfactory. |
