Abstract

A study was carried out to investigate the feasibility of using a packed bed electrochemical reactor with low-through porous graphite electrodes to remove either cyanide and/or zinc ions simultaneously from wastewater. The effects of cell current density, flow rate, pH and inlet concentration on removal efficiency and current efficiency of either cyanide ion or zinc ion and combination of both ions removal were studied. It was found that the removal efficiency of cyanide ions increases with cell current density, pH and feed flow rate. Several cell arrangements were investigated. It was found that the vertical arrangement of cells is better than the horizontal arrangement. For zinc removal it was found that removal efficiency of zinc ions increases with cell current density. For a combination of both ions it was found that removal efficiencies of zinc and cyanide increase with flow rate, current density and inter concentration. Current efficiency of zinc removal increases with current, flow rate and zinc ion concentration but remains constant with pH change.
