Scientists built a reusable magnetic material that removed more than 95% of microplastics from water

Researchers at RMIT University built a reusable magnetic material that removed more than 95% of microplastics and nanoplastics from water within one hour.

The material captures plastic particles down to 30 nanometers and also removes heavy metals like mercury, chromium, and copper, as well as drug residues and industrial dyes.

Early testing showed promise in removing some PFAS chemicals, but researchers note PFAS removal is still at an early stage.

The magnetic powder can be recovered with magnets after use, reducing waste and operational costs for water treatment.
