Abstract
Mixed organic‐inorganic‐bentonite complexes were obtained by adsorption of cetyltrimethyl‐ammonium cations onto Al‐hydroxy‐montmorillonite prepared with bentonite Algerian deposits. These mixed complexes are characterized by a large interlamellar spacing of about 0.9 nm and small surface area. Their adsorption affinities toward some first class hazardous pollutants i.e. chlorinated phenols were investigated. Adsorption data suggest that their sorptive capacities were enhanced in comparison with natural occurring materials.
