Abstract
A model is presented that is applicable to a wide range of peak-shaped voltammetric signals. It may be used, via curve-fitting, to resolve s everely overlapped peaks, irrespective of the degree(s) of reversibili ty of the electrode processes. The resolution procedure has been thoro ughly tested for several voltammetric and polarographic techniques (di fferential pulse, square wave and pseudo-derivative normal pulse), usi ng reversible, quasireversible and irreversible electrochemical system s.
