Abstract

The occurrence of the reduction of ClO4- ions in the course of the dissolution (corrosion) of Co was indicated through the study of the adsorption of radio labelled (36Cl) Cl- ions. A detailed analytical study determining the Co2+ and Cl- content of the solution phase furnished firm evidences that under suitable chosen experimental conditions the 4Co+ClO4-+8H+= 4Co2++Cl-+4H2O reaction could be as important as the Co+2H+=Co2++H2 reaction considered in the literature as the only reaction path.
