It has been found that zeolite based nanocomposites exhibit a high arsenic removal efficiency. In this study, natural zeolite of clinoptilolite was modified with Fe3O4 nanoparticles, and then this nanocomposite was converted to granules using ionic gelation method. Based on the results, 0.1 and 0.7 g/l of adsorbents dose were chosen as optimal values for the powders and granules to reach the maximum arsenic removal, respectively, which are considerably lower than those reported for the adsorbents in the literature. This suggests that newly prepared low cost Fe3O4 coated clinoptilolite can be considered as a potential adsorbent in the remediation of aqueous waste contaminated with arsenic.
