A Northwestern University-led research team now reports an inexpensive and renewable material that rapidly removes PFOA from water. The novel treatment effectively eliminates the micropollutant to below 10 parts per trillion, far below Environmental Protection Agency and all state health advisory limits.
Dichtel, the Robert L. Letsinger Professor of Chemistry at Northwestern’s Weinberg College of Arts and Sciences, believes the material can support water purification efforts to rid drinking water of PFOA and perhaps other per- and polyfluorinated alkyl substances (PFASs), such as perfluorooctanesulfonic acid (PFOS).
The PFOA material and Dichtel’s polymer technology are being developed for commercial use by CycloPure, Inc., a company co-founded by Dichtel.
The study, co-authored by Dichtel, Damian Helbling, assistant professor of civil and environmental engineering at Cornell University, and members of their research groups at Northwestern and Cornell, recently was published by the Journal of the American Chemical Society.
