This review paper explores recent advances in the use of nanomaterials for dye adsorption, focusing on three innovative approaches: surfactant exfoliated graphene, modified expanded graphite nanomaterials, and graphene-coated cotton. Surfactant exfoliated graphene, produced via surfactant-assisted ultrasonic exfoliation, demonstrates exceptional adsorption capacity for ionic dyes, driven primarily by electrostatic interactions. This method achieves a maximum adsorption capacity of 782.3 mg/g for methylene blue, highlighting its efficiency and rapid adsorption kinetics. Modified expanded graphite nanomaterials exhibit enhanced adsorptive properties due to their increased surface area and tailored functional groups, which facilitate high dye uptake and improved removal efficiency. Additionally, graphene-coated cotton, prepared through a cost-effective and eco-friendly process, offers excellent absorption performance for oils and organic solvents, with potential scalability for large-scale environmental remediation applications(Cotton). These studies collectively underscore the potential of graphene-based nanomaterials as effective adsorbents for the removal of organic dyes from wastewater, providing valuable insights for future research and industrial applications.
