An in-situ FTIR study of the adsorption behaviour of cyanide ions on a platinum electrode
Abstract
In-situ FTIR studies of the adsorption behaviour of cyanide ions on a platnium electrode in aqueous K2SO4 solution indicate that cyanide is not adsorbed on the electrode, as reported for other metals; instead, CN– appears to be oxidized to OCN–, thereby liberating H+ ions, which convert the SO42– ions to HSO4–.
