Abstract
A general CV peak fitting method based on the NLLSRC algorithm was implemented and its capability to provide geometrical shape parameters, correlable to kinetic, thermodynamic and operational quantities, was tested, both on simulated and real data sets. As in XPS and in DTA/DSC a base line proportional to peak area was tested, even if no theoretical support seems to be available in an electrochemical environment. Using a phoenomenological approach, the empirical validity of such a simple baseline was noted and a quantitative procedure based on area measurements was found to be more precise and easier than usual methods.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
