Abstract The widespread presence of microplastics and nano plastics in water bodies has emerged as a critical environmental concern due to their persistence, toxicity, and potential risks to human health and aquatic ecosystems. Conventional water treatment methods often exhibit limited efficiency in removing these ultra-fine particles, especially at the nanoscale. This study focuses on the application of magnetic nanoparticles (MNPs) as an innovative and efficient approach for the removal of micro and nano plastics from contaminated water.
Magnetic nanoparticles, owing to their high surface area, strong adsorption capacity, and ease of separation using an external magnetic field, offer a promising solution for targeted pollutant removal. In this method, surface-functionalized MNPs interact with plastic particles through electrostatic attraction, hydrophobic interactions, or chemical bonding, leading to aggregation and subsequent magnetic separation. Experimental parameters such as pH, nanoparticle dosage, contact time, and agitation speed are optimized to achieve maximum removal efficiency.
The results indicate that MNP-based treatment can significantly enhance the removal of both microplastics and nano plastics compared to traditional techniques, with advantages including rapid separation, reusability of nanoparticles, and reduced sludge generation. This study highlights the potential of magnetic nanoparticle technology as a cost-effective, scalable, and environmentally sustainable method for advanced water purification.
Overall, the proposed approach addresses a major gap in current water treatment systems and contributes to the development of efficient strategies for mitigating plastic pollution in aquatic environments.
