Spline wavelet in the resolution of overlapping voltammetric peaks

Spline wavelet transform is used to resolve overlapping voltammetric peaks. A suitable resolving factor is chosen to multiply the filters of spline wa velet and make it a peak resoluter. Simulated overlapping voltammetric peak s are processed by the peak resoluter and satisfactory results are obtained . Base-line separation can be achieved, the relative errors of peak positio n are less than 3.0%, and the relative errors of peak area are less than 5. 0%. The effect of different resolving factors and spline wavelet basis are discussed. To lest the procedure, two systems, cadmium (II)indium (III) and lead (II)-thallium (I), are used.
