Adsorption Kinetics of Basic Blue-41 Dye onto Synthetic Foam-Shaped Zeolite ZSM-5

The synthesized foam-shaped zeolite ZSM-5 material was characterized by X-ray diffraction (XRD), (FTIR) spectroscopy, scanning electron microscopy (SEM) and BET techniques. The adsorption performance of the material were evaluated for the basic blue-41 dye removal. A maximum removal amount of 161.29 mg/g at 323K was achieved. Experimental kinetic data of this new adsorbent fitted well with the pseudo-second order model. The apparent diffusion coefficient values was in the range of 10^-12 cm^2/s. The regeneration tests revealed that the adsorption efficiency of the foam-shaped zeolite sample was retained after three regeneration runs, with a loss of only 6% of the original adsorbed value.
