The role and significance of graphene oxide in the remediation of micro- and nanoplastics from the environment
AI summary Read the abstract
This review examines how graphene oxide, a carbon-based material with a very large surface area, can be used to remove microplastics and nanoplastics from water. Graphene oxide showed impressive removal capacity for polystyrene microplastics through adsorption. The technology could be an important tool for developing more effective water treatment systems that protect people from microplastic contamination.
Micro- and nanoplastics (M/NPs) are widespread environmental pollutants arising from the increased use of plastics, presenting significant threats to human health and freshwater ecosystems. These particles are derived from both secondary and primary sources, including the breakdown of larger plastic debris and industrial abrasives, and cosmetics. After being released, M/NPs move through the air, water, and soil, where they persist, bioaccumulate, and interact with biological systems, potentially causing toxicity, inflammation, and oxidative stress. This study thoroughly addresses the origins, environmental routes, and health impacts of M/NPs, as well as the most current remediation strategies. Physical, chemical, biological, and hybrid therapeutic techniques are evaluated critically, with adsorption receiving special attention due to its efficiency and simplicity of usage. Graphene oxide (GO), a potential carbon-based adsorbent with a large surface area, several oxygen-containing functional groups, and a remarkable removal capability (up to 617.28 mg g-1 for polystyrene microplastics), receives special attention. Along with a comparison with other adsorbents, the review discusses GO's structural properties, synthesis procedures (including the Hummers' process), and adsorption mechanisms. This study contributes to the development of cutting-edge, environmentally friendly water treatment technologies by combining new research and emphasising the potential of GO-based materials for effective M/NP remediation in aquatic settings.

AI summary Read the abstract
Researchers tested three forms of graphene — graphene oxide, graphene foam, and reduced graphene oxide — as filters for removing microplastics from water, achieving removal efficiencies of up to 95% in lab conditions. Reduced graphene oxide performed best, though all three materials showed promise as next-generation water treatment adsorbents that could help tackle microplastic contamination at the source.
Study on the adsorption of polystyrene microplastics by three-dimensional reduced graphene oxide
AI summary Read the abstract
Three-dimensional reduced graphene oxide was shown to adsorb polystyrene microplastics from water effectively, with a maximum capacity of 617 milligrams per gram, driven by strong pi-pi interactions between the carbon structures of both materials. The method worked well in both tap and lake water, making it a potentially practical tool for microplastic removal.
