Electrolytic removal of zinc using a flow-through cell with a malgamated copper screen cathode

الملخص EN

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.
