Abstract

A polarographic (dc and dpp) and kinetic studies reduction of monoethyl fumarate (MEF) has been carried out in the 0–11 pH range. Effects of pH, drop time and temperature on the limiting current, half-wave potentials, and E vs. log[ i/(i L−i )] plots are shown. From the C−E curves obtained, the adsorption of MEF on the mercury electrode in acid medium is shown to be present. The Tafel slopes and reaction orders with respect to MEF and H + ion are obtained at potentials corresponding to the foot of the waves. Reaction mechanisms are thus proposed in this zone of potentials.
