| Abstract: | The principal component analysis method was applied to singlepoint pH titration. The method can determine individual component concentration of the mixture of very weak acids or bases simultaneously. The principle of the method was discussed and the constant matrix of principal component analysis was established. Eight ternary mixed samples of very weak acid and twelve quaternary mixed samples of very weak bases were determined with satisfactory results. |
