Abstract
AbstractThe adsorption of phenol by various amine‐activated montmorillonites has been studied and the resulting expansion of the basal spacings of the derivatives measured. The results indicate that the expansion of the basal spacings of the primary amine derivatives is strictly limited, whereas with the quaternary ammonium‐treated clays a much greater expansion is found, and a correspondingly larger amount of phenol is adsorbed.A comparison of the amount of phenol adsorbed by the quaternary ammonium compound in solution and when the latter is ion‐exchanged on to the clay, shows that a considerable increase in adsorption occurs in the latter case.
