Electrode Method

The Cr6+/Cr3+ reduction in aqueous solution is studied in the presence of sulfate and chloride ions by the rotating disc electrode method. In the low chromic acid concentration region, the results exhibit some differences in relation to those obtained using more concentrated solutions. However, it is demonstrated that in the presence of sulfate and chloride ions there is a chemical reaction preceding the electrochemical process, confirming a previous suggestion. Results for Cr6+/Cr3+ reduction process in perchloric acid medium at various temperatures are presented and a reduction mechanism is suggested.
