This work deals with the cathodic stripping peaks of manganese dioxide deposited on a disk electrode by pre-electrolysis. Coulometric and spectrophotometric methods and electrochemistry using a rotating ring-disk electrode are used to explain the formation of the more positive peak as a result of the reduction of nonstoichiometric oxygen formed in the manganese dioxide film on the disk electrode.
