Description
Asmaa Jrad and co-authors build a spongy framework material that both spots and soaks up a notorious water pollutant, in a 2024 paper. The pollutant is PFOA, one of the PFAS family of chemicals tied to health and environmental harm. Their material is a covalent organic framework carrying a positive charge, made by a simple sound-based method.
The framework detected PFOA down to very low levels and pulled in more than 2,600 milligrams per gram within seconds, working over repeated cycles. In column tests it removed the pollutant fully at levels found in the environment. Simulations showed uptake happens in two phases, helped by the pollutant clumping through water-shy interactions. The authors offer the design as a template for fighting PFAS pollution.
