The upshot of the presence of selenium in the electrolytic solution as an impurity over a
concentration range of 0 to 1000 mg dm− 3 during the electrodeposition of copper from
sulfate solutions has been investigated in the present study. Higher concentrations of
selenium (> 50 mg dm− 3) in the copper sulfate solutions significantly reduce the current
efficiency and quality of the copper electrodeposits and increase the energy consumption of
the electrodeposition process. Cyclic voltammetric studies revealed that selenium, when …
