Abstract

To investigate the effects of multiple weak interactions on the binding of phenolic compounds by polymeric adsorbents, macroporous polystyrene (PS) resin and PS-based adsorbents with different hydrogen-bond acceptor atoms (PS-CH 2(-OCH2CH2)n-OCH3, n = 0, 1, 2, and 3, denoted as PS-EG0, PS-EG1, PS-EG 2, and PS-EG3) were prepared. The phenol adsorption strength order on these adsorbents was PS/PS-EG0 < PS-EG 1 < PS-EG2 < PS-EG3, indicating that the adsorption on PS and PS-EG0 was driven by hydrophobic and π-π interactions, and the adsorption on PS-EG1, PS-EG2, and PS-EG3 was driven by a hydrogen bond in addition to hydrophobic and π-π interactions. PS-EG2 may adsorb a second phenol molecule on each binding site and PS-EG3 may adsorb second and third ones. The adsorption strength of resorcinol increased in the order of PS, PS-EG 1, and PS-EG2, indicating that the adsorption was driven by 0, 1, and 2 hydrogen bonds in addition to hydrophobic and π-π interactions. Similarly, the adsorption of phloroglucinol on PS, PS-EG 1, PS-EG2, and PS-EG3 was driven by 0, 1, 2, and 3 hydrogen bonds in addition to hydrophobic and π-π interactions because the adsorption strength increased in this order. © 2006 Wiley Periodicals, Inc.
