This study aims to develop new technology concepts using Cu-SiO2 nano-catalyst electrodes for treating industrial mine wastewater by reducing chlorine ions present in the wastewater discharged from the Eshidiya mine in South Jordan. Electrochemical mechanisms, reaction kinetics, electrode regeneration, and efficiency of the electrode were evaluated. The optimal condition for Cu-SiO2 nano-catalyst electrodes entailed examining their impact on chloride removal efficiency through the investigation of variable scan rates, initial chloride concentrations, pH concentrations, current density, and electrode sensitivity. The Brunauer-Emmet-Teller (BET) results revealed that the surface area and pore volume of the Cu-SiO2 were 470.7309 cm2/g and 0.296093 cm3/g, respectively. The cyclic voltammetry (CV) results indicated that the chloride ion at a scan rate of 5.0 V/s reduced the anodic peak potential by 0.11 V and decreased the current density to 5.8 mA/cm2. The Tafel plot shows three significant peak potentials at − 0.005, 0.052, and 0.104 V. The i-t curve showed that the electrode reached an equilibrium activity that required regeneration to be activated by reversing the voltage from 0.71 to 0.71 V.Click here for Link
