The effect of B on copper in the reduction and oxidation process in electrolyte A was investigated. Electrochemical measurements like cyclic voltammetry (CV),EIS and potentiodynamic polarization techinique were used to study the electrochemical behavior of copper deposition; the distribution of cathode current density was tested through hull cell; the IR spectra of the complex and the Absorbance curves of the electrolyte to analysis was used to characterise the coordination compounds. The results showed that: the addition of B could expand A electrolyte cathode current density, inhibit the copper electrodeposition, promote the dissolution of copper anode, and inhibit the liberation of hydrogen; the reduction process of copper control by electrochemical occurred at a glassy carbon electrode gradually transformed into diffusion control with the B concentration increasing in solution. The addition of B in electrolyte A was mainly to form the CuTEA(OH)2 coordination compounds, and to adsorb on the electrode surface to affect the electrochemical reaction. |
