New and more precise acidity measurements may help make PFAS easier to track. Per- and polyfluoroalkyl substances (PFAS) are nicknamed “forever chemicals” in part because their acidity helps them linger in the environment. Many of these toxic chemicals are strongly acidic, so they readily shed protons and take on a negative charge, which lets them […]



Summary

Precise acidity measurements of PFAS chemicals can help researchers better understand their behavior and track them in the environment. The “forever chemicals” persist due to their acidity, easily shedding protons and becoming negatively charged. This negative charge influences how PFAS interact with soil, water, and other substances, affecting their movement and fate. Accurate acidity measurements, specifically pKa values, provide crucial insights into these interactions, enabling more effective monitoring and potentially leading to better strategies for removing or mitigating PFAS contamination.
