The influence of static magnetic field on the removal of microplastics by bacterial-algal symbiotic system in simulated seawater

Removal of microplastics from water by using magnetic sedimentation

AI summary · Read the abstract

"Researchers demonstrated that magnetic Fe-C-NH2 nanoparticles added to water can attach to polyethylene and PET microplastics, forming heteroaggregates that are then removed by a gradient magnetic field, achieving effective extraction of both plastic types from model aqueous suspensions. This green magnetic sedimentation approach offers a scalable, chemical-free pathway for removing microplastics from drinking water or wastewater effluent, with direct implications for reducing human ingestion of plastic particles."
