Chitosan and Ferrite Nanoparticles Modified Zeolite (ZSM-5) as Adsorbent for the Removal of Acid Red Dye from Water

Abstract

The present study involved the synthesis and characterization of nanocomposites (NCs) consisting of MgFe₂O₄-chitosan-ZSM-5 zeolite (MgF-Cs-Ze), NiFe₂O₄-chitosan-ZSM-5 zeolite (NiF-Cs-Ze), and MgFe₂O₄@ NiFe₂O₄-chitosan-ZSM-5 zeolite (MgF@NiF-Cs-Ze). These NCs were investigated for their potential application as effective adsorbents in various environmental contexts. In order to investigate the composition and physical properties of the NCs, XRD, FT-IR, SEM-EDX, and TEM techniques were utilized. The present study is aimed at evaluating acid red (AR) dye adsorption behavior from aqueous solutions onto MgF-CS-Ze and NiF-CS-Ze NCs under different experimental circumstances. The study revealed that the NCs MgF-CS-Ze and NiF-CS-Ze exhibited maximum capacity for adsorption of 55.55 mg g^-1 and 41.66 mg g^-1, respectively, in that regard when tested with AR dye. These findings underscore the significant adsorption capabilities of these NCs. Examining the adsorption kinetics revealed that AR dye adsorption process followed the pseudo-second-order kinetic model. Resulting from thermodynamic studies, it was discovered that the adsorption of AR dye onto MgF-CS-Ze and NiF-CS-Ze NC process was an exothermic and spontaneous.
