Influence of Chloride Anions on the Mechanism of Copper
We investigate the influence of chloride ions in a broad range of chloride concentrations on the kinetics and mechanism of copper electrodeposition from sulfate-based acidic electrolytes. Chloride ions influence copper deposition through two competitive effects: at low concentration (few mM), chloride ions depolarize the Cu reduction process, while higher …

Behavior of Copper in Acidic Sulfate Solution: Comparison with Acidic
Abstract. The anodic polarization behavior of copper in a 0.1 M sulfuric acid (H2SO4) + 1 M sodium sulfate (Na2SO4) solution (pH = 2.0) was studied at room temperature under quiescent and stirred conditions. The behavior was compared with aqueous equilibria via construction of a potential-vs-pH (E-pH) diagram for the copper-sulfate-water (Cu-SO42−-H2O) …
