A review of nanomaterials with excellent purification potential for the removal of micro- and nanoplastics from liquid
AI summary Read the abstract
This review summarizes how specialized nanomaterials can be used to remove microplastics and nanoplastics from water, working as tiny filters, chemical catalysts, or absorbent surfaces. Traditional water treatment methods struggle with these very small plastic particles, but engineered nanomaterials show promise for capturing them more effectively. The authors also emphasize the importance of reducing plastic pollution at its source alongside developing better cleanup technologies.
Microplastics (MPs) and nanoplastics (NPs) pose a significant threat to human health due to their slow degradation, high toxicity, and potential to react with organic pollutants, forming even more hazardous substances. However, traditional methods for removing MPs/NPs have limitations. Nanomaterials are extensively utilized in water treatment for their easily modifiable properties and ability to effectively bind to contaminants. This review critically examines various nanomaterials employed as adsorbents, catalysts, and membranes for the removal of MPs and NPs. By delving into the sources of these pollutants, we aim to encourage further research focusing on source reduction. Furthermore, key areas for potential future research directions are highlighted.

AI summary Read the abstract
This review examines how nanomaterials, tiny engineered particles with high surface area and reactivity, can be used to remove microplastics from water more effectively than traditional methods like filtration and sedimentation. While promising, these technologies face challenges including high production costs, potential toxicity of the nanomaterials themselves, and difficulty scaling up from lab to real-world applications. Improving these methods is important because current water treatment often fails to remove the smallest and most harmful microplastic particles.
