Abstract |
Water molecules may force the hydrophobic perfluoroalkyl chain of perfluorocarboxylic acids (PFCAs) to aggregate at hydrophobic siloxane patches (Si–O–Si) of the silica surface despite electrostatic repulsion between surface silanol (SiO−) and the carboxylate (–COO−) headgroup of PFCA. Acidic pH and background cations promote the adsorption further by reducing the anion–anion Coulomb repulsion. |
