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 severely overlapped peaks, irrespective of the degree(s) of reversibility of the electrode processes. The resolution procedure has been thoroughly tested for several voltammetric and polarographic techniques (differential pulse, square wave and pseudo-derivative normal pulse), using reversible, quasireversible and irreversible electrochemical systems.
