Abstract

Abstract: The methods of image processing and edge detection by wavelet transform were introduced into chemistry for determining potentiometric titration end-points.This method was used to deal with the experiment data derectly without introducing artificial error factors in calculation. The accuracy of calculation results can get to the experiment limit automati-cally, and the titration end-points can be determined easily by this method. Very satisfactory results were obtained in the calculation.

Key words: Potentiometric titration, Titration end-points, Wavelet transform, Edge detection
