ClearGreen Synthesis and Characterization of Fe-Ti Mixed Nanoparticles for Enhanced Lead Removal from Aqueous Solutions
Researchers developed iron-titanium mixed oxide nanoparticles using an environmentally friendly synthesis method and tested their ability to remove lead from water. The nanoparticles achieved up to 98.1% lead removal efficiency and could be regenerated and reused for multiple treatment cycles. While not directly about microplastics, this green nanotechnology approach addresses the broader challenge of removing persistent contaminants from water.
Conversion of the styrofoam waste into a high-capacity and recoverable adsorbent in the removing the toxic Pb(II) from water media
Researchers chemically modified waste styrofoam — a common plastic pollutant — into a magnetic adsorbent capable of removing toxic lead (Pb²⁺) ions from water, achieving around 90% removal efficiency. This work shows that plastic waste can be repurposed into useful water-treatment materials, offering a dual benefit of reducing plastic waste while cleaning heavy metal contamination.
Facile synthesis and characterization of Fe3O4/analcime nanocomposite for the efficient removal of Cu(II) and Cd(II) ions from aqueous media

Exploring Humic Acid as an Efficient and Selective Adsorbent for Lead Removal in Multi-Metal Coexistence Systems: A Review
This review examines how humic acid, a natural substance found in soil and water, can selectively remove lead from water contaminated with multiple heavy metals. The research explores how to enhance humic acid's ability to capture lead ions specifically, including through chemical activation and pH control. While focused on heavy metals, the work is relevant to microplastics research because microplastics can concentrate and transport lead and other heavy metals, and better lead removal from water could reduce this combined pollution threat.
Magnetic nanocomposites: innovative adsorbents for antibiotics removal from aqueous environments–a narrative review
This review examines how magnetic nanocomposite materials can be used to remove pharmaceutical pollutants from water. While not directly about microplastics, the technology is relevant because microplastics in water often carry pharmaceutical residues that conventional treatment cannot fully remove. Better water filtration methods like these could help reduce human exposure to the cocktail of pollutants that microplastics transport.
Removing micro- and nanoplastics (MNPs) from water via novel composite adsorbents: A review
Researchers reviewed advances in composite materials — including carbon-based, magnetic, and metal-organic framework (MOF) materials — designed to adsorb and remove micro- and nanoplastics from water, finding that each type offers performance advantages over traditional adsorbents but also faces challenges around cost, scalability, and environmental safety. The review calls for future materials that are stable, sustainable, and practical for large-scale water treatment.

Advancements in Adsorption Techniques for Sustainable Water Purification: A Focus on Lead Removal
This review surveys recent advances in adsorption techniques for removing lead from contaminated water, covering materials from traditional metal oxides to newer options like chitosan, zeolites, and carbon-based structures. Researchers evaluate how well each material performs and highlight promising alternatives that are more sustainable and cost-effective. While focused on heavy metals rather than microplastics, the study contributes to the broader effort of developing better water purification methods.

Remediation strategies for micro/nanoplastic pollution using magnetic nanomaterials
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.
Microplastics and other pollutants in the aquatic environment: study of interactions and new removal strategies
Researchers evaluated iron magnetic nanoparticles (MNPs) with varying surface modifications -- bare Fe3O4, TEOS-coated, and TEOS+MPS-coated -- for removing four types of microplastics (Nylon 6, PTFE at two sizes, and PMMA) from water, assessing how surface chemistry and synthesis time affect removal efficiency.
Surface wettability control and electron transport regulation in zerovalent iron for enhanced removal of emerging polystyrene microplastics-heavy metal contaminants
Researchers developed a specially engineered iron-based material that can simultaneously remove microplastics and heavy metals from wastewater by combining a water-repelling outer layer with efficient electron transfer at its core. In tests, the material removed over 99% of polystyrene microplastics and prevented the secondary release of heavy metals that often ride along on plastic particles. This addresses the concern that microplastics act as a "Trojan horse," carrying toxic metals into water supplies and living organisms.
Application of Surface-Modified Natural Magnetite as a Magnetic Carrier for Microplastic Removal from Water
Researchers modified natural magnetite — a common iron mineral — with a hydrophobic chemical coating so it would stick to plastic particles in water, then used magnets to pull everything out. When applied to six common plastic types including polyethylene and polystyrene, finely-ground treated magnetite removed over 90% of the microplastics. This low-cost, naturally-sourced approach could offer a scalable method for cleaning microplastics from water supplies.
