Electrochemical remediation of copper(II) from an industrial effluent. Part I: monopolar plate electrodes

Many studies indicate that flow-through reactors with three-dimensional electrodes can be successfully used for metal removal from dilute streams, but they present high capital costs. So the simplest titanium and stainless steel AISI 904L plate were chosen as cathode materials in tank reactors. A three cell plant was used for cathodic deposition of copper from an industrial effluent containing copper (II). The influence of the flow rate and the initial copper concentration on the removal efficiency and current yield was studied.
