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 thematerial were evaluated for the basic blue-41 dye removal. a maximum removal amount of 161.29 mg/g at 323kwas achieved. experimental kinetic data of this new adsorbent fitted well with the pseudo-second order model. theapparent diffusion coefficient values was in the range of 10^-12 cm^2/s. the regeneration tests revealed that theadsorption efficiency of the foam-shaped zeolite sample was retained after three regeneration runs, with a loss ofonly 6% of the original adsorbed value.
