Abstract
The adsorption of Sunfix Blue SF-RL dye onto methyl methacrylate/ Na-Y-Zeolite (MMA/Na-Y-Z) composite was investigated in aqueous solution in a batch system with respect to contact time, pH, adsorbent dosage and temperature. Physical characteristics of (MMA/Na-y-Z) composite such as Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) were obtained. Langmuir and Freundlich adsorption models were applied to describe the equilibrium isotherms and the isotherm constants were determined. The activation energy of adsorption was evaluated for the adsorption of Sunfix Blue SF-RL dye onto (MMA/Na-Y-Z) composite. The pseudo-first-order and pseudo-second-order kinetic models were used to describe the kinetic data. The dynamic data fitted the pseudo-second-order kinetic model for the adsorption of Sunfix Blue SF-RL dye. The activation energy (Ea), change of free energy (∆G), enthalpy (∆H) and entropy (∆S) of adsorption were also evaluated for the adsorption of Sunfix Blue SF-RL dye onto (MMA/Na-Y-Z) composite. The thermodynamics of the adsorption indicated spontaneous and endothermic process for Sunfix Blue SF-RL dye. The results indicate that (MMA/Na-Y-Z) composite could be employed as low-cost material for the removal of dyes from industrial wastewater.
