Abstract
Tetraethylammonium cations were shown to inhibit the potentiostatic iron dissolution because they increase the electrode surface coverage (θ) with hydrogen atoms. It was found that the iron dissolution rate becomes independent of θ above a critical concentration (C) of absorbed hydrogen, but decreases with an increase in the θ/C ratio. The latter is in turn determined by the bath composition and a way of iron hydrogenation. The partial rate constants of electrolytic hydrogen evolution were calculated by a method considering the electrode surface coverage with a cathodic inhibitor.
