Abstract

The aim of this work was to establish an electrolytic method for the removal of
zinc from waste water using a flow-through cell with amalgamated copper screen
cathode .The performance of the electrolytic reactor were investigated by using different
of electrolyte flow rates (60, 120, 180, 240, 320L/h) and different initial concentration of
zinc solutions(48, 96, 150mg/L).A synthetic solution was processed using boric acid
(0.1M) plus potassium chloride (0.1M) as the supporting electrolyte .The electrolytic cell
employed a constant potential of -1.4V vs. SCE in the controlled potential mode.
Dimensionless Sherwood and Reynolds numbers were correlated to characterize
the mass transport properties of the reactor, and they where fitted to the equation:
Sh = 0.6835Re0.3895 Sc1/ 3 For 1< Re < 6.5, 700 < Sc < 1390
