MOLECULAR DESIGN OF EFFECTIVE AND VERSATILE ADSORBENTS FOR EX SITU TREATMENT OF AFFF-IMPACTED GROUNDWATER
Michalsen, M., J.A. Field, E. Christie, M. Khazaee, and C. Ng.
SERDP Project ER18-1417, 31 pp, 2019

Results of this limited-scope project confirmed the potential of protein-based sorbents for 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 to tune an adsorbent, by incorporating multiple protein-based moieties and/or 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 forms the basis of a robust and powerful design framework for developing protein-based sorbents for PFAS water treatment. https://www.serdp-estcp.org/content/download/49855/491219/file/ER18-1417%20Final%20Report.pdf
