Copper removal from industrial wastewater: A

2017-12-25  The most important electrochemical methods used for heavy metal ions removal are electrocoagulation and electrodialysis. Electrodialysis is considered to be as an electrochemical process to separate copper ions from industrial wastewater, where copper ions exchange through the membranes under the electric field . Further, the electric field starts when the reactions at the surface of the
