New method removes microplastics ‘in minutes’ – study

SEOUL – Researchers at Pusan National University say they have developed a water-treatment method that removes microplastic pollution in minutes by drawing the particles together with a magnetic field.

The approach, presented in the peer-reviewed Journal of Environmental Management, is said to eliminate more than 95% of micro and nanoplastics within 10 minutes by using plate-shaped iron-oxide magnetic nanoparticles.
