Abstract
The present study involved the synthesis and characterization of nanocomposites (NCs) consisting of MgFe 2 O 4 ‐chitosan‐ZSM‐5 zeolite (MgF‐Cs‐Ze), NiFe 2 O 4 ‐chitosan‐ZSM‐5 zeolite (NiF‐Cs‐Ze), and MgFe 2 O 4 @ NiFe 2 O 4 ‐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.
