Studies of Electrooxidation of Dextrose in Neutral Media
Source abstract
Abstract
Electrooxidation of dextrose on platinized platinum electrodes has been studied in phosphate buffer at p H 7.4. Rest potentials are interpreted as mixed potentials. Galvanostatic curves have been observed to exhibit oscillatory voltage behavior. In the range of potentials investigated gluconic acid is observed as the reaction product and is found to inhibit oxidation of dextrose due to adsorption on the electrode surface. From the measurements of the adsorption characteristics of the acid, the oscillatory voltage behavior of the galvanostatic curves have been ascribed to kinetic effects of formation of the product and the potential dependence of its adsorption.
