The removal of methylene blue dye from aqueous waste by Magnetic nanoparticle activated carbon (MNPAC) was investigated. Magnetic nanoparticle activated carbon (MNPAC) was synthesized by mixing aqueous suspension of activated carbon (AC) and Fe3O4 by chemical co-precipitation method. This Magnetic Nanoparticle Activated carbon (MNPAC) was characterized by X-ray Diffraction (XRD), Transmission Electron Microscope (TEM), Fourier Transform Infrared Spectroscopy (FTIR) and Vibrating Sample Magnetometer (VSM). The result of XRD characterization was indicated Fe3O4 as the product. FT-IR Spectrum of MNPAC shows the presence of various surface groups. TEM image of the Fe3O4 showed nanoparticles Fe3O4 have the mean diameter 5-20 nm. MNPAC exhibits super magnetic properties under external magnetic field with saturation magnetization value of 22.80emu/g at room temperature. The adsorption equilibrium was represented with Langmuir, Freundlich, and BET isotherm models. The adsorption data shows that the adsorption capacity was investigated by absorbing Methylene blue (MB) dye from aqueous waste, which demonstrated an excellent adsorption capacity of MNPAC (500 mg g-1). A Langmuir kinetic model is fitted well for methylene blue adsorption on MNPAC.
