Abstract: The classical Fourier self deconvolution has the problem in selecting simulated function and filter function, so its application in resolving overlaped peaks is limited. In this paper, using coarser approximation obtained after wavelet transform as line shape function, a new electroanalytical method, Fourier self-deconvolution oscillographic chronopotentiometry is founded. Experimental results show that this method can not only improve the resolution power and sensitivity, but also make selection of parameters in the processing of Fourier self deconvolution easy and simple.
