An Antidote to Firefighting Foam Contaminant PFAS

Lundquist and Chalker field sample.jpg
South Australian scientists have found a clever way to clean up water contaminated by a toxic compound found in old firefighting foam.
Researchers from Flinders University and the University of South Australia have found a way to absorb PFAS (toxic polyfluorinated alkyl substances) pollution using waste cooking oil and sulphur combined with activated carbon.
Study co-director Dr Justin Chalker from Flinders University joins Jennie Lenman to discuss.

The research paper, “Polymer supported carbon for safe and effective remediation of PFOA- and PFOS-contaminated water”, by Nicholas Lundquist, Martin Sweetman, Kymberley Scroggie, Max Worthington, Louisa Esdaile, Salah Alboaiji, Sally Plush, John Hayball and Justin Chalker, has been published in the published in ACS Sustainable Chemistry & Engineering.

The project was a collaboration funded by the South Australian Defence Innovation Partnership, with further support from industry partners Puratap and the Salisbury Council. Co-directors of the study were A/Prof Sally Plush and Prof John Hayball at UniSA and Dr Justin Chalker at Flinders University.
