Abstract

The structural evolution of cost-effective organo-clays (Bentonite modified with different loadings of HDTMA (hexadecyltrimethylammonium bromide)) from 50 to 200% of the CEC is investigated and linked to the adsorption uptake and mechanism of an important industrial dye (Bezathren Red (BzR)) from the aqueous solution. The prepared materials were characterized by X-ray diffraction XRD, infrared spectroscopy measurements FT-IR, and thermal analysis ATG. The intercalation of the surfactant cations in the interlayer spaces of bentonite (BA) was confirmed by the increase of the basal spacing from 1.13 to 1.78 nm. The kinetic data were found to follow the pseudo-first-order model. The equilibrium data were analyzed using the Langmuir and Freundlich models. The Langmuir isotherm model is the most suitable to describe the BzR dye adsorption. The calculated Langmuir maximum adsorption capacities increased from zero to 111.1 mg/g.
