Tóm tắt

Single-solute batch kinetic and isotherm experiments were conducted in Type 1 (18.2 MΩ·cm resistivity) water supplemented with 10 mM carbonate buffer (pH 7.75, 25 °C) for nine drinking water relevant perfluoroalkyl chemicals and three bituminous-coal based granular activated carbons (GACs). Except for perfluorooctane sulfonic acid (PFOS), mass transfer was well represented by a film diffusion model, which estimated a film diffusion coefficient (k
