Electrochemical remediation of copper(II) from an industrial effluent. Part II: three-dimensional foam electrodes

A batch recycle removal of copper ions from an industrial effluent by means of copper foam cathodes was tested. A constant current of 750 A was applied to the cell in order to perform the reduction. Copper depletion was investigated at different solution flow rates and a removal greater than 98% was obtained with a flow rate of 1000 l:h. The influence of initial metal concentration on copper deposition and current efficiency is also discussed
