The increasing global demand for clean water necessitates the development of efficient and sustainable filtration technologies. Graphene oxide (GO) membranes have emerged as promising candidates for water purification due to their exceptional mechanical strength, tunable interlayer spacing, and high permeability combined with selective molecular sieving properties. This study presents a systematic fabrication process of graphene oxide membranes and evaluates their effectiveness for removing contaminants from water. The GO membranes were prepared using vacuum filtration followed by chemical reduction to enhance stability. Characterization by SEM, XRD, and FTIR confirmed the membrane morphology, structure, and functional groups. Water permeability tests and contaminant rejection experiments demonstrated high flux rates and effective removal of heavy metals, dyes, and salts. The results highlight the potential of GO membranes as a sustainable and efficient solution for clean water production.
