Electrochemical study and XPS analysis of chalcopyrite dissolution in sulfuric acid in the presence of ethylene glycol

The effect of ethylene glycol (EG) on chalcopyrite dissolution was studied in 1 M sulfuric acid at an open circuit potential and 25 °C. Electrochemical studies were performed having employed potentiodynamic and electrochemical impedance spectroscopy (EIS) techniques. Based on the results, the additi...
