In this article, material magnetic aerogel on graphene was prepared success by hydrothermal method and its properties were evaluated using X-ray diffraction (XRD), scanning electron microscopy/X-ray energy dispersive spectroscopy (FESEM/EDX), infrared spectroscopy (FT-IR), and vibration sample magnetization (VSM). The results show that the magnetic iron oxide nanoparticles have a uniform morphology, an average particle size of about 50-100 nm, are well dispersed on the graphene base, and the material's magnetism reaches 20.66 emu/g. The experimental data were analyzed by Langmuir, Freundlich, Tempkin and DubininRadushkevich (D-R) models of adsorption. Utilizing experimental data, pseudo-first-order and pseudosecond-order kinetic models were evaluated. The 2,4-dichlorophenoxyacetic acid (2,4-D) adsorption on the material was fitted to Freundlich isotherm and the maximum adsorption capacity was found to be 102.04 mg/g.
