Resolution of Overlapping Neopolarographic Peaks of Two Species

Abstract

Abstract: A new method for resolution of neopolarographic two-component peaks by multiple linear regression is presented. The method is based on the linear superposition of neopolarograms. The overlapping waves of two species can be resolved and the concentrations of them can be determined by the standard addition and the multiple linear regression. The principle of the method is simple. Its program is fast when executed. It is shown that the method possesses an acceptable accuracy and high resolution when the simulated data being handled. The method has been verified futher by the application of the method to staircase sweep neopolarography of In³⁺/Cd²⁺and Pb²⁺/Tl⁺systems.

Key words: Neopolarography, Overlapping peaks, Fourier transform
