Abstract : Universiti Pendidikan Sultan Idris |
In this work higher Cu2+ removal efficiency was achieved by graphene oxide GO-based electrode with the constant magnetic field (CMF)-assisted electrodeposition system. The GO was initially synthesized by the electrochemical exfoliation method in the electrolyte containing custom-made surfactant. The as-prepared GO solution was then spray coated on the pre-heated stainless steel-cathode before annealed at 400°C for 1 hour. GO-based electrode with CMF-assisted electrodeposition system was successful removed 89.1% of Cu2+ from aqueous solutions as compared to the electrode without GO of only 75.5% of Cu2+ removal within a fixed 3 hours’ time. The efficient of Cu2+ removal by GO-based electrode was believed due to the high specific surface area of GO that increases the accommodation of the active species (Cu2+) at the electrode surfaces. In the meantime, it was found that the presence of CMF of 23 Gauss parallel to cathode surfaces enhances the convection and mass transport of Cu2+ charged species to the electrode as compared to the absence of the CMF on an electrodeposition system. This phenomenon was due to the Magneto-Hydrodynamics (MHD) effect of CMF which is based on the Lorentz force that increases the Cu2+ deposition efficiency by reducing the diffusion layer thus increasing the ions transfer into the electrical double layer. The electrodes before and after Cu2+ deposition was examined by electron microscopy, energy dispersive x-ray, and Raman spectroscopy, and the concentration of remaining Cu2+ in the solution was analyzed using atomic absorption spectroscopy. From the analysis done shows that the GO-based electrode with CMF-assisted electrodeposition system pave a new and pragmatic route for efficient removal of heavy metal ions.
