For the first time, this paper presents spline wavelets application to
step; voltammetry signals. The method has advantages as follows: taki
ng short time to deal with all data, having no necessary to find:the r
elations with variables in any other systems, handling the target func
tions and initial conditions directly from sample data and obtaining f
ew data necessarily. Some reasonable noises are added to the theoretic
al data. Signal-to-noise ratio varies from 0.1 to 100. The result is s
atisfactory and exciting even if the S/N ratio decreases to 0, 15, Exp
erimental data from a low concentration of Ti(VI)-H2C2O4 and W(VI) + M
o(VI)-HAPP-KClO3 system are utilized to demonstrate the application of
wavelet analysis. The agreement between the theoretical and experimen
tal results is excellent,
