Fe₃O₄@ABDA nanocomposite as a new adsorbent effective removal of methylene blue dye: isotherm, kinetic, and thermodynamic study

ABSTRACT

In this study, Fe3O4@ABDA nanocomposite was fabricated and used as an efficient material for elimination of MB dye from aquatic environment. The structural characterization, surface morphology, and thermal stability of Fe3O4@ABDA nanocomposite were achieved by using FTIR, TEM, TGA/DTG, XRD, and zeta potential. The impact of different parameters such as pH values, equilibrium time, temperature, and initial MB concentration on the elimination MB onto Fe3O4@ABDA nanocomposite was studied. The equilibrium time was reached in 180 min at pH 7 at 25°C. The maximum removal capacity for MB could reach 123.5 mg/g. The removal mechanism was mainly assigned to columbic and π – π combination among the molecules of MB and the Fe3O4@ABDA surface.
