Remediation strategies for micro/nanoplastic pollution using magnetic nanomaterials
Summary
This review surveys recent developments in using magnetic nanomaterials, such as iron oxide nanoparticles and magnetic composites, to remove micro- and nanoplastics from water and soil. These materials can capture plastic particles through adsorption, help clump them together for removal, or even break them down, and they can be magnetically recovered for reuse. The study highlights that magnetic nanomaterials offer a promising approach for cleaning up plastic pollution, though challenges remain in scaling up for real-world use.
The widespread presence of microplastics (MPs) and nanoplastics (NPs) in the terrestrial and aquatic environments is posing a great threat globally. MPs/NPs pervade our environment in different forms and sizes. Their widespread presence can negatively affect aquatic organisms, soil, wildlife, birds, and humans. As a result, it becomes critical to develop remediation options for MPs/NPs. Among numerous materials, magnetic nanomaterials are one of the potential thrust areas for mitigating MP/NP pollution. In the present review, we discuss the recent developments in applying magnetic nanomaterials (such as nanoscale zero-valent iron, iron oxide nanoparticles, magnetic nanocomposites, spinel ferrites, and magnetic perovskites) for MP/NP removal from various matrices. Different methods including adsorption, coagulation removal, and degradation have been highlighted in detail to remediate MPs/NPs. Then, the performance comparison between different technologies and magnetic nanomaterials has been done to highlight their relative efficiencies, limitations, and suitability for MP/NP remediation. Finally, the limitations, practical challenges in real contaminated ecosystems, and future solutions for the use of magnetic nanomaterials are discussed.
