Abstract

The present study comprises the surfactant-based modified adsorbents as inorgano–organo composites for the removal of dyes. It was depicted that 0.05 g of modified clay could be efficiently used to adsorb >90% of dye (100 mg/L). The kinetic models (pseudo-first order, pseudo-second order, intraparticle diffusion model) and isothermal models (Langmuir, Freundlich, Temkin) were also studied to examine the adsorption mechanism. Pseudo second-order kinetic model and Langmuir isothermal model fitted well with adsorption of dyes. The thermodynamic ((Formula presented.)) parameters were also studied and negative value of ((Formula presented.) and positive value of ((Formula presented.)) indicates the spontaneity of adsorption.
