Abstract
The adsorption of phenol and 4-chlorophenol on oxides in aqueous solut ions is strongly influenced by the cationic surfactant hexadecyltrimet hylammonium chloride. At surfactant concentrations below the CMC, stro ng synergistic interaction effects on the adsorption are observed, whe reas above the CMC, solubilisation of the phenols in micelles becomes an important competing effect. An approach is described for calculatin g the partition coefficients of the phenols between the bulk phase, th e surface and the micelles.
