Abstract

ORGANO CLAYS ARE POWERFUL ADSORBENTS FOR A WIDE VARIETY OF ENVIRONMENTAL APPLICATIONS. THE SURFACE PROPERTIES OF BENTONITE CAN BE GREATLY MODIFIED WITH A SURFACTANT BY SIMPLE ION-EXCHANGE REACTIONS. THIS IS FAVOURED BY VANDERWAALS INTERACTION BETWEEN ORGANIC SURFACTANT CATIONS AND THE REDUCED SOLVENT SHIELDING OF THE IONS IN THE INTERAMOLECULAR ENVIRONMENT. LARGE ORGANIC CATIONS (CATIONIC SURFACTANTS) OF THE FORM (CH3)3N+R, WHERE R IS AN ALKYL HYDROCARBON, OCCUPY THE EXCHANGE SITES OF THE BENTONITE CLAY AND HENCE THE SURFACE AREA IS INCREASED. RAW BENTONITE WAS MODIFIES WITH CETYLTRIMETHYL AMMONIUM BROMIDE TO FORM ORGANIC-MODIFIED BENTONITE. THE PRODUCT INVESTIGATED BY ELEMENTAL ANALYSIS, FT-IR, X-RAY DIFFRACTION. THE RESULTS CONFIRMED THE PRESENCE OF CETYLTRIMETHYL AMMONIUM BROMIDE ON THE SURFACE OF BENTONITE. REMOVAL OF AN AZO DYE ONTO MODIFIED BENTONITE FROM AQUEOUS SOLUTIONS WAS INVESTIGATED [1-3].THE KINETIC DATA WERE ANALYZED USING PSEUDO-FIRST ORDERAND PSEUDO-SECOND-ORDER KINETIC MODELS. THE ADSORPTION KINETICS CAN BE PREDICTED BY THE PSEUDO-FIRST-ORDER MODEL.
