Abstract:
Results of this limited-scope project confirmed the potential of protein-based sorbents for per-and polyfluorinated alkyl substances PFAS remediation by identifying, through a complementary model-experiment approach, proteins that associate strongly with both long-and short-chain PFAS. Of particular benefit is the ability we identified to tune an adsorbent, by incorporating multiple protein-based moieties andor by use of strategic changes in feed composition ionic strength, pH, to address a wide variety of PFAS structures. The combination of molecular modeling and batch testing used here thus forms the basis of a robust and powerful design framework for developing protein-based sorbents for PFAS water treatment.
