| Abstract: | The right angle triangular/semicircular
cylindrical promoters are inserted at the bottom of a rectangular electrolytic
cell and limiting current data are measured at the copper microelectrodes fixed
on an electrode support. The effects of flow rate of the electrolyte,
height/radius of the promoter and spacing between the promoters on mass
transfer are investigated. The electrolyte consisted of 0.01 N potassium
ferricyanide, 0.01 N potassium ferrocyanide and 0.5 N sodium hydroxide. The
mass transfer coefficient is increased with the increased height/radius of the
promoter. Increased spacing between the promoters resulted in lowering of the
mass transfer coefficient. |
