The applicability of CM-β-CD-Fe3O4NPs synthesis for the removal of Aluminum ion from wastewater was studied. The active sites and morphology structure of CM-β-CD-Fe3O4NPs synthesis were analyzed using BET, FT-IR, XRD, SEM, and XPS respectively. The effect of independent variables namely pH, adsorbent dosage, contact time, Al (III) ion concentration in solution, were investigated through batch experiments, and to be 7, 50 mg L-1, 0.1 g and 90 min for the adsorption of Al (III) ion onto CM-β-CD-Fe3O4NPs sorbent were found respectively. The adsorbed Al (III) ion onto the CM-β-CD-Fe3O4NPs showed excellent fitting to the pseudo-first-order adsorption kinetic with a correlation coefficient value of 0.999.Meanwhile, the experimental equilibrium data were fitted to the conventional isotherm models accordingly. Freundlich isotherm has good applicability for the experimental data with a maximum adsorption capacity (qmax) of 35.88 mgg-1 for Al (III) ion onto CM-β-CDFe3O4NPs. The overall results confirmed that CM-β-CD-Fe3O4NPs could be a promising adsorbent material for Al (III) ion removal from wastewater treatment.
