Hydrophobic Ion Pairing with Cationic Surfactant Modifies Surface Activity and Colloidal Behavior of PFAS

Quaternary ammonium compounds (QACs) are increasingly used to enhance the removal of per- and polyfluoroalkyl substances (PFAS), particularly short-chain compounds, through hydrophobic ion pairing (HIP). Here, we investigated how HIP with cetyltrimethylammonium chloride (CTAC) influences the interfacial and colloidal...

Occurrence of per- and polyfluoroalkyl substances (PFAS) and their precursors in biosolids across 15 U.S. states

The US Environmental Protection Agency (EPA) draft sewage sludge risk assessment indicates that land application of biosolids containing as little as 1 ng/g of perfluorooctanoate (PFOA) or perfluorooctane sulfonate (PFOS) may exceed human health risk thresholds. This study provides updated measurements of per- and poly...
