Abstract
The US Environmental Protection Agency recently released strict regulations limiting per- and polyfluoroalkyl substances (PFAS) in drinking water. In response, this study used activated carbons derived from biomass waste components for effective water treatment. By varying the composition of feedstock mixtures, perfluorobutane sulfonic acid adsorption efficiencies ranged from 31 to 98 %, indicating that biomass structure influences PFAS sorption. Activated carbon from a feedstock mixture of 50 % lignin, 35 % cellulose nanocrystals, and 15 % cellulose nanofibers achieved over 98 % removal of three regulated and four unregulated PFAS compounds without requiring additives or surface functionalization.
