Abstract

The various reasons for current efficiency losses in indirect electrochemical processing are considered. Using the Cr(VI) oxidation ofo-toluene sulphonamide as a model, it is shown that accretion of organic residues is an important factor contributing to current efficiency losses. Other evidence is provided to suggest that film formation on the electrode surface acts selectively to promote oxygen evolution rather than Cr(III) re-oxidation.
