Commercially available natural bentonite clay samples obtained from Oil India Limited, India, werepurified via standard sedimentation process followed by screening with the help of siphoning processby applying Stock’s law to obtain < 2 μm fraction of the clay. The Na+, Mg2+ and Cu2+ cations wereincorporated in the interlayers of the bentonite clay by applying different chemical procedures. Modifiedbentonite clays thus obtained were characterized by PXRD, HRTEM, FTIR analysis, DRS analysis,TGA, SEM & EDX analysis, and BET surface area analysis.
