Palladium-coated membrane destroys over 90% of PFAS in water

Researchers at Arizona State University and international partners built a catalytic hollow-fiber membrane lined with palladium nanoparticles that breaks down PFAS. In a 58-day trial it removed over 90% of each of six priority compounds and 83% of total fluorine.

• Hollow-fiber membrane with palladium splits carbon-fluorine bonds using atomic hydrogen
• Over 90% of each of six priority PFAS compounds removed in a 58-day continuous trial
• Total fluorine removal reached 83%
• Palladium costs about $50,000 per kg, so the reactor would pair with existing filtration
