Abstract: This work describes the synthesis and characterization of Fe, Al pillared bentonite and its application in Rhodamine B adsorption. The materials were prepared using different ratio nOH-/(nFe3+ + nAl3+) of Fe, Al pillaring solution. The samples were characterized by X-ray diffraction (XRD). The results showed the insertion of aluminium and iron pillaring cations into clay interlayer space with an increase of d001 value compared with that of Wyoming bentonite. The Rhodamine B adsorption data was analyzed by both Freundlich and Langmuir isotherm models and the data was well fit by the Langmuir isotherm model. The maximum adsorption capacity of Rhodamine B over Fe,Al-bentonite derived from the Langmuir equation were 63.69 mg.g-1. Kinetic data correlated well with the pseudo-second-order kinetic model.
