Electrochemical evaluation of copper deposition with gas sparging

The influence of gas sparging during copper electrolysis was studied using standard electrochemical techniques. The polarization behaviour of acid copper electrolytes was determined in the presence and absence of gas sparging on vertical electrodes. Tracer ion techniques were employed to determine the effect of gas sparging and forced circulation of the electrolyte on the mass transfer characteristics of the system. In addition to the potentiodynamic scans, 3-h copper deposits were produced for morphology and orientation studies. The effect of current density and temperature on deposition were also studied. The polarization experiments have shown that a mass transfer component becomes evident at about 40% of the limiting current density at which point the deposit becomes noticeably rougher.
