A team in Erlangen used functionalized iron oxide nanoparticles to bind a broad range of PFAS and fluorine-containing microplastics, then remove them with a magnet. In tests on river water, laundry wastewater and a contaminated drinking water source, PFAS fell by 87%, below Germany’s 100 nanograms per liter limit.

Nanopartículas magnéticas reducen PFAS en agua contaminada

PHYS

Un equipo de Erlangen usó nanopartículas funcionalizadas de óxido de hierro para unir una amplia gama de PFAS y microplásticos con flúor, y retirarlos con un imán. En pruebas con agua de río, aguas de lavado y una fuente de agua potable contaminada, los PFAS bajaron un 87%, por debajo del límite alemán de 100 nanogramos por litro.
