ABSTRACT:
Adsorption of an anthraquinone dye Alizarin Red S onto biosorbent of mustard husk has been studied on aqueous solutions. The batch adsorption experiments were conducted using simulated aqueous solutions and the effects of initial dye concentration, pH of solution, contact time and temperature were investigated. The prepared biosorbent was characterized using FTIR, SEM, elemental analysis and through the determination of pHzpc. The equilibrium data were modeled with Langmuir and Freundlich isotherms. The rates of adsorption were found to confirm to the pseudo-second-order kinetics with good correlations (R2>0.99). The thermodynamic studies showed that the Alizarin Red S-biosorbent system is spontaneous, exothermic and favourable in nature.
