Magnetic solution removes toxic "forever chemicals" from water in seconds
Scientists in Australia have developed an intriguing new technique for removing toxic “forever chemicals” from water. Adding a solution to contaminated water coats the pollutants and makes them magnetic, so they can easily be attracted and isolated.
In tests with small samples of PFAS-laden water, the team found that the technique could remove over 95% of most PFAS molecules, including over 99% of GenX – a particularly problematic chemical – within 30 seconds.
