Flinders University team reports nano-cage adsorbent that captures short-chain PFAS in water tests

Researchers at Flinders University say they have developed an adsorbent material that removed more than 98% of short- and long-chain PFAS—including hard-to-capture short-chain variants—in laboratory flow-through tests using model tap water. The approach embeds nano-sized molecular cages into mesoporous silica and, in the experiments reported, could be regenerated while remaining effective over at least five reuse cycles.
Defekte Abwassersysteme, rasante Verstädterung und industrielle Verschmutzung verwandeln Gautengs Flüsse in eine Umwelt- und Gesundheitskrise. Große Wasserläufe wie Jukskei, Klip und Hennops transportieren unbehandelte Abwässer und Schadstoffe in größere Systeme wie den Vaal River. Ein aktueller Bericht hebt unsichere Bakterienwerte in vielen Gewässern der Provinz hervor.
