<p>A modified inorgano-organoclay or organoclay incorporates reactive intercalates for the chemicorption and immobilitation of organic and inorganic contaminants, the clays supporting the growth of microorganisms in a biofilm capable of bioremediation. The intercalation additives preferably comprise a combination of an aluminium hydroxide polymer, a quaternary ammonium salt, and a transition metal salt. Modified clays treated with a transition metal salt and/or a pillaring agent are also disclosed. Typically, the transition metal salt is ferric chloride and the pillaring agent may comprise a metal hydroxide polymer, oxides of silicon and titanium, or transition metal clusters. A method of treating contaminated material using a modified clay is also claimed.</p> |
