The aim of this study was to fabricate and characterize graphene oxide (GO) based electrodes for two types of home-developed water treatment system, namely electrodeposition (ED) and capacitive deionization (CDI) for copper ions (Cu2+) and methylene blue (MB) dye removal. Electrochemical exfoliation was utilized to synthesize GO using custom-made triple-tails (TC14) surfactant. Hydrazine hydrate was utilized as reduction agent to produce TC14-rGO. The TC14-GO and TC14-rGO were then coated via spray coating method on stainless steel (SS) which further utilized as electrodes in ED water treatment system. Meanwhile for CDI system, the TC14-GO sample was sprayed and immersed in activated carbon fiber cloth (ACFC) electrodes. The TC14-GO-based electrodes were characterized using electron microscopy, energy dispersive X-ray, high resolution transmission electron microscopy, X-ray diffraction, fourier transform infrared spectroscopy, UV-Vis spectroscopy and micro-Raman spectroscopy. The atomi.....
