Effect of added cobalt ion on electro-deposition of copper from sulfate bath using graphite and Pb–Sb anodes

The influence of alloying elements on the electrochemistry of lead anodes for electrowinning of metals: A review

“…PbO 2 formation is promoted over other potentially deleterious oxides. The cathode is less contaminated with Pb and the deposit is smoother, brighter and has a reduced nodular size (Panda et al, 2009). Finally, corrosion at the anode may be reduced by effective addition of Co 3 O 4 on to the PbO 2 layer.…”

Morphology of Copper Deposits Obtained by Metallic Electrodeposition

“…The morphology of copper electrodeposits obtained from synthetic solutions was widely investigated by Nikolic et al (2008Nikolic et al ( , 2012 and Panda et al (2009). Controlled shape metallic particles have received tremendous attention due to unique electronic, magnetic, optical and catalytic properties; further they have a wide range of application, such as chemical biosensing, catalysis, photonic, optoelectronics (Ko et al (2009)).…”

Electrochemical and physical characterisation of lead-based anodes in comparison to Ti–(70%) IrO2/(30%) Ta2O5 dimensionally stable anodes for use in copper electrowinning

“…The voltammetric charge, obtained by integration between the hydrogen and the oxygen gas evolution region of a CV curve, has been shown to be proportional to the EASA of metal oxide electrodes, and also gives a measure of the number of active sites [7,41,42]. All experiments were carried out in 0.5 M sulphuric acid at a scan rate of 20 mV s -1 .…”

“…These include replacement of the conventional anode reaction with an oxidation reaction of SO 2 [4], or Fe 2? ions [5,6], addition of Co 2? ions to the electrolyte in the conventional cell [7] and the use of alternative anodes [3,[8][9][10][11].…”
