The time-dependence of molecular weight of gelatin, the cathode potential and the polarization resistance were investigated during long-term electrolysis of Cu to evaluate the degradation of gelatin and polyethylene glycol (PEG) added to the electrolyte for Cu electrorefining. Gelatin and PEG acted as a polarizer for Cu deposition, shifting the cathode potential to less noble direction. The polarization caused by the additives gradually decreased with increasing the electrolysis duration. The effective duration of additives significantly depended on the molecular weight and was longer in PEG-containing solution than in gelatin-containing solution. The molecular weight of gelatin in electrolyte decreased with increasing the electrolysis duration. Particularly, the molecular weight of gelatin was much more decreased at anode than cathode. Even in the case without electrolysis, the molecular weight and polarization effect of gelatin decreased with increasing the time. The decrease in molecular weight of gelatin brought about the shift of the cathode potential to noble direction, showing that the molecular weight of degraded gelatin had a close relation to the deposition potential of Cu. The Cole-Cole plots obtained by AC impedance techniques showed that the polarization resistance for Cu deposition in PEG-containing solution decreased with increasing the electrolysis duration.
