The chemicals known as PFAS are considered a severe threat to human health. Among other things, they can cause liver damage, cancer, and hormonal disorders. Researchers have now developed a new, efficient method of filtering these substances out of drinking water.
They rely on so-called metal-organic framework compounds, which work much better than the materials commonly used to date. Even extremely low concentrations of PFAS in the water can still be captured.
The team led by Nebojša Ili from the TUM Chair of Urban Water Systems Engineering and Prof. Soumya Mukherjee, a former Alexander von Humboldt postdoctoral researcher at the TUM Chair of Inorganic and Organometallic Chemistry during the study period and now Assistant Professor of Materials Chemistry at the University of Limerick, identified water-stable metal-organic framework compounds made of zirconium carboxylate as particularly effective PFAS filters.
Researchers from the TUM School of Natural Sciences worked together with colleagues from the TUM School of Engineering and Design and simulation experts from the TUM School of Computation, Information, and Technology to develop and research the new filters. Prof. Roland Fischer, Chair of Inorganic and Organometallic Chemistry, emphasizes:"When solving such major challenges, experts from a wide range of disciplines have to work together. You simply can't get anywhere on your own.
