Copper deposition at segmented, reticulated vitreous carbon cathode in hull cell

Copper deposition at segmented, reticulated vitreous carbon cathode in hull cell
The electrodeposition of copper from an acid sulphate solution has been studied in a Hull cell fitted with four types of cathode; a carbon plate or a reticulated vitreous carbon (RVC) sheet was used either in a continuous or segmented form. The rates of mass transport to the planar plate and RVC electrodes have been compared in static and stirred electrolytes containing 50, 75 and
100 mmol dm23 CuSO4 in 0?5 mol dm23 Na2SO4 at pH 2 and 298 K. The cathodes were divided into 10 equal sections and current vs. potential curves were obtained for each section at a constant current up to 140 mA. The current distribution over the cathodes followed a logarithmic
decay with distance along the cathode; segments nearest to the anode experienced the highest rate of copper deposition.

Abstract

The electrodeposition of copper from an acid sulphate solution has been studied in a Hull cell fitted with four types of cathode; a carbon plate or a reticulated vitreous carbon (RVC) sheet was used either in a continuous or segmented form. The rates of mass transport to the planar plate and RVC electrodes have been compared in static and stirred electrolytes containing 50, 75 and
100 mmol dm23 CuSO4 in 0?5 mol dm23 Na2SO4 at pH 2 and 298 K. The cathodes were divided into 10 equal sections and current vs. potential curves were obtained for each section at a constant current up to 140 mA. The current distribution over the cathodes followed a logarithmic
decay with distance along the cathode; segments nearest to the anode experienced the highest rate of copper deposition.
