A new magnetic Fe3O4/MO-intercalated-LDH composite has been synthesized by combination of Fe3O4, layered double hydroxide (LDH) and methyl orange (MO). Fe3O4/Zn2CrLDH and Fe3O4/MO-intercalated-LDH were obtained via two-step microwave hydrothermal and anion exchange method. X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy and vibrating sample magnetometer (VSM) were conducted to characterize the as-prepared samples. The latter exhibited that basal spacing of Zn2Cr-LDH is 1.18 nm. The value of saturation magnetization (Ms) is 20.5 emu/g. In addition, the amounts of adsorbed MO reached 1.54 mmol/g. Therefore, the material shows several advantages for the removal of pollutants.
