Abstract
The synthesed foam-shaped zeolite ZSM-5 material w:::as char:::acterized by X-ray diffraction (XRD), (FTIR) spectroscopy, scanning electron microscopy (SEM) and BET technique. The adsorption performances of the material were evaluated for the basic blue-41 dye removal. A maximum removed amount of 161.29 mg/g at 323K was achieved. Experimental kinetic data of this new adsorbent fitted well the pseudo-second order model. The apparent diffusion coefficient values was in the range of 10-12 cm2/s. The regeneration tests revealed that the adsorption efficiency of the foam-shaped zeolite was retained after three regeneration runs, with a loss of 6% of the original adsorbed value.
