Effect of vibrating disc electrode on ionic mass transfer in an electrolytic cell

In the present investigation, a vertical disc electrode was vibrated in a rectangular electrolytic cell. The cell consisted of equimolal potassium ferricyanide and ferrocyanide electrolyte with excess indifferent electrolyte, sodium hydroxide. The mass transfer data were obtained on the disc electrode by varying the amplitude of vibration (0.033 to 0.089 m), frequency of vibration (2.93 to 16.16 Hz) and diameter (0.0125 to 0.0315 m) of the disc electrode. The mass transfer coefficient was increased with the decrease in the diameter of the disc electrode. The mass transfer coefficient was enhanced from 12 to 52 fold due to vibration.
