Coadsorption of low molecular weight aromatic and aliphatic alcohols and acids with the cationic surfactant, CTAB, on silica surfaces

Wangchareansak, Thipvaree; Keniry, Max; Liu, Guangming; Craig, Vincent


We have investigated the coadsorption of a range of small molecules with the cationic surfactant CTAB to silica surfaces over a range of concentrations and CTAB to solute ratios and compared the coadsorption with adsorption in the presence of the salicylate ion. We find that molecules with aromatic character and molecules with double bonds are most favorably adsorbed, and we attribute this to cation-π bonding between the surfactant headgroups and the π orbitals of the unsaturated bonds of the...[Show more]
