Fe3O4-NanoGraphene Platelets (NGP) composites with different surface area were successfully synthesized using sol gel method. The inverse cubic spinel structures as well as graphitic like structure from NGP were detected using X-Ray Diffraction (XRD) Measurement, while the ferromagnetic behavior for all samples were detected using Vibrating Sample Magnetometry (VSM) measurement. The vibrational mode for all samples were characterized using Fourier Transform Infrared Spectroscopy (FT-IR), and thermal stability for all samples were characterized using Thermogravimetric Analysis (TGA). The adsorption process were tested using methylene blue (MB) as a model of organic pollutant. The result showed that the higher NGP surface area could enhance the adsorption capacity of the samples. The kinetic model of adsorption shows that the adsorption process of Fe3O4-NGP materials followed the second order kinetic reaction. The reusability of adsorbent were also performed to analyze the stability of the adsorbent.
