OSTI ID:63779
The sorption at room temperature of benzene and naphthalene from water and from methanolater mixtures by four different organophilic clays has been determined. The organophilic clays were prepared from Wyoming montmorillonite by replacing the natural exchange ions of the clay by the quaternary ammonium ions TMA (tetramethylammonium), TMPA (trimethylphenylammonium), HDTMA (hexadecyltrimethylammonium), and BDTDA (benzyldimethyltetradecylammonium). Of these organoclay, TMPA-montmorillonite has the greatest sorptive ability for naphthalene and is followed in order of decreasing sorptive ability by BDTDA-, HDTMA-, and TMA-montmorillonite. TMA-montmorillonite is much more effective as a sorbent for benzene than it is for naphthalene. For benzene sorption, TMPA-montmorillonite is most effective, followed in order by TMA- and BDTDA-montmorillonite.
