• The introduction of inorganic and organic contaminants into aquatic systems by waste streams released from urban, industrial, agricultural, and other sources has become a global problem. Heavy metal ions and synthetic dyes are the most common contaminants in natural aquatic systems, causing a variety of life-threatening problems in humans and other living things. Graphene oxide-based nanocomposite materials have been widely used in the treatment of water/wastewater containing heavy metal ions and dye pollutants because of their high surface areas, excellent mechanical strength, and adaptability to different functional groups. Adsorption-based removal of heavy metal ions and synthetic dyes from aqueous media, as well as photo-degradation of dyes using efficient adsorbents or photo-catalysts like graphene-based nanocomposite materials, has a lot of benefits, including cost-effectiveness, applicability in large-scale operations, efficiency, and reutilization. The majority of graphene or reduced graphene oxide nanocomposite materials can remove or degrade over 90% of heavy metal ions and dye pollutants from wastewater. According to a literature review, some of these materials decontaminated wastewater to the extent of 99 or 100%. The potential of graphene oxide based nanomaterials in the treatment of water/wastewater, significant features of graphene based nanomaterials, adsorption and photo-catalytic processes, future aspects, and some relevant current investigations are all discussed in this review.
