The Role of Electrolyte Additives on Passivation Behaviour During Copper Electrorefining
, 2000 Additives, such as chloride, thiourea and glue, are commonly added to electrorefining electrolyte to control deposition structure and morphology. Very few studies have been performed to observe their effects on anode passivation.
