Abstract

Abstract:
The sorption of indigo dye onto methymethacrylate/sodium-Y-Zeolite composite had been evaluated in watery solutions studying different parameters namely, period of the experiment, pH, adsorbent dosage and thermal effect on the experiment. Different properties of methymethacrylate/sodium-Y-Zeolite composite as forier-transformation IR spectroscopy, X-rays deffraction had been investigated. Langmier and Frendlich sorption imitations had been utilized for describing equilibrial isotherm. In addition, evaluation of the activating force of sorption has been carried out regarding the sorption of indigo dye on the surface of methymethacrylate/sodium-Y-Zeolite composite. Kinetics information of the reaction were also studied.. These experimentally obtained information was nicely compatible and consistent with the pseudo-second-order kinetics for adsorption of indigo dye. The activating force (Ea), difference in liberated energies (∆G), entalpy (∆H) and enthropy (∆S) of sorption methodology had been determined regarding the sorption of the indigo dye via composites.methymethacrylate/sodium-Y-Zeolite composite. The termodynamics of the sorption proved that the process had been both spontaneously and endothermically happening.
The results indicated that methymethacrylate/sodium-Y-Zeolite composite would be successfully applied as efficient, reproducible, and inexpensive adsorbent regarding the sorption of indigo dye from industrial wastewaters.
