Abstract
The adsorption of fatty acids and phenols on high surface polymeric sorbents with polar surfaces has been examined. The results obtained from equilibrium experiments with acetic and butyric acids, phenol, and substituted phenols in aqueous, toluene, and hexane solutions show that the new polar polymeric sorbents have a considerable adsorption capacity in non-aqueous solvents. The shapes of the binding isotherms of substitued phenols from aqueous solution on a new high surface area (860 m2/gm) hydrophobic adsorbent suggest that a next-neighbor interaction exists between molecules bound on adjacent sites. The equation described by A. Fowler and E. A. Guggenheim, who considered such interactions, fits the experimental data.
