Abstract A study of the fundamentals of adsorption of amphiphilic organic cations on natural and pristine surfaces was conducted to elucidate the factors that influence the extent of adsorption and indirect effects of adsorption of organic cations: the competitive adsorption of organic cations and metal cations and enhanced adsorption of hydrophobic organic compounds on mineral surfaces coated with organic cations. The sorbents studied were kaolinite, montmorillonite, silica, alumina, a soil, and two aquifer materials. The distribution ratio of the alkylpyridinium depended strongly on the nature and concentration of inorganic cations in solution, but solution pH had little effect. The adsorption isotherms were distinctly nonlinear. The adsorption of dodecylpyridinium in the presence of various concentrations of slats was described quantitatively with a multisite competitive ion-exchange model. Dodecylpyridinium was found to displace Cu(II) effectively from Lula aquifer material when the surface concentration of dodecylpyridinium is within 10-100% of the adsorption maximum. Dodecylpyridinium on Lula aquifer material enhanced the sorption of chlorobenzenes.
