摘要：

This study aims to evaluate the effect of tow surfactants hexadecyl(trimethyl)azanium;bromide (CTAB) and 1-butyl-3methylimidazol-3-ium;chloride (BMIMCl) intercalation in bentonite (Bt) on methylene blue dye adsorption.The modified clays were characterized in detail using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA). The XRD analysis showed the increase of basal spacing ranged between 20.99 angstrom and 14.19 angstrom for Bt-CTAB and BtBMIM respectively. The FTIR is another tool to investigate the presence of organic matter on the clay surface. More specifically, the results showed that the formation of new bands of vibrations (1400- the adsorption of methylene blue. In presence of surfactant the maximum adsorption capacities of Bt-CTAB and Bt-BMIM mg center dot g-1, respectively. According to the results algerian bentonite sample tested in this paper can effectively remove methylene blue from aqueous solutions.
