Abstract

A high-charge smectite from Arizona and a low-charge smectite from Wyoming were used to prepare homoionic tetramethylammonium (TMA)-clay complexes. The adsorption of the organic vapors by the dry TMA-smectite samples was strong and apparently consisted of interactions with both the aluminosilicate mineral surface and the TMA exchange ions in the interlayers. The low-charge Wyoming TMA-smectite was a highly effective adsorbent for removing benzene from water and may be useful for purifying benzene-contaminated water. -from Authors
