This review comprehensively examines the utilization of carbon-based nanomaterials, specifically graphene oxide (GO) and carbon nanotubes (CNTs), in advanced wastewater treatment applications. GO CNTs demonstrate exceptional efficacy adsorbing a broad spectrum organic compounds hazardous microorganisms due to their unique physicochemical properties, such as large specific surface areas, high aspect ratios, versatile chemical modifications enabled by functional groups. is characterised abundant oxygen-containing groups, including hydroxyl, carboxyl, epoxy, which enhance its hydrophilicity adsorption potential for cationic pollutants. Meanwhile, CNTs, available single-walled (SWCNTs) multi-walled (MWCNTs), are noted tubular structure, tensile strength, significant electrical conductivity, making them highly effective molecules heavy metals.
