Linear sweep voltammetry of glyoxylate on a stationary mercury electrode showed strong adsorption effects in addition to kinetic control because of the hydration of the aldehyde groups. The methods of Shain were used to minimise the adsorption and to determine the kinetic function at pH 9.0. The dehydration rate constant was found to be 1.14 ± 0.03 s-1.
