摘要：

A novel method for finding of end paints of acid-base potentiometric titration by using wavelet transform strategy was developed to determination of amount of very weak acids of orthoboric acid and phenol. The comparison of the results obtained by proposed method and the conventional methods or rational spline function method showed that the wavelet transform technique in combined with potentiometric titration method for determination of very weak acid has the advantage of rapidity and accuracy. It may provide a new way for automatic titration of very weak acids using potentiometer with computer.
