Abstract: Smectite clay materials with interlayered structure have ability to be modified by intercalation of functional group. This study presents the study the thermodynamic and kinetics of the insertion butyl Pyridinium Ionic Liquid (IL) into the interlayer space of smectite clay. Chemical interaction of intercalated IL and its potency for adsorption application was intensively simulated for the adsorption of chromate ion. Preparation of IL-intercalated smectite was conducted using saponite and montmorillonite minerals. Physicochemical character of functionalized materials was studied by XRD, FTIR, gas sorption analyser and SEM-EDX. Materials adsorptivity towards chromate ion was performed in a batch adsorption system. IL-intercalated smectite was successfully prepared and it is found that the intercalation obey chemical adsorption with an endothermic condition. The increasing basal spacing of saponite by the intercalation is higher compared to that of montmorillonite. The IL-intercalated clays demonstrated the high adsorptivity for chromate ions.
