Paper Title
Highly Efficient Adsorbent for Anionic Dye using a Synthesized Zeolite P from Coal Fly Ash

Abstract
In this work, the Coal Fly Ash (CFA), collected from a generation power plant, was converted into a zeolitic material following a novel preparation method. The X-Ray Diffraction (XRD) analysis was used to determine that the type of the zeolite synthesized was a zeolite P. The obtained Zeolite P was also characterized by the scanning electron microscopy (SEM). The zeolite P was applied to remove the anionic dye Congo Red (CR) from waste water. The effect of the different factors on the adsorption of CR have been studied: pH (3-10), initial concentration (250-2000mg/L), adsorbent dosage (0.1-0.5g/L) and contact time (0-20min). The modeling study indicates that the pseudo second order and Freundlich models fitted well the kinetic and equilibrium data, respectively. An extremally high capacity of adsorption was found for the adsorption of the CR on zeolite P with a maximum of 7819mg/g.
