Effects of sodium lignosulfonate on bismuth electrochemical deposition on copper surfaces from HCl-NaCl-BiCl3 solution

H.E. Yun-long, X.U. Rui-dong, H.E. Shi-wei et al. · 2018 · International Journal of Electrochemical Science

The effects of sodium lignosulfonate (SLS) on bismuth electrochemical deposition on copper surfaces from HCl-NaCl-BiCl3 solution were investigated. Cyclic voltammetry studies indicated that the Bi3+ ions could be reduced electrolytically to bismuth on the surface of copper in the presence of different concentrations of SLS and that 0.3 g/L of SLS was beneficial for the electroreduction of Bi3+. The cathodic polarization study indicated that SLS had a noticeable effect on the Tafel slope and exchange current density but no significant effect on the transfer coefficients.
