AB  - In this study, carbonaceous nanomaterials (Activated Carbon (AC), Graphene Oxide 
      (GO) and Porous Graphene Oxide (PGO)) were synthesized and attached to Fe(3)O(4) 
      magnetic powder for the effective removal of synthetic Methyl Orange (MO). AC and 
      GO were successfully conjugated with Fe(3)O(4) whilst PGO was not due to its surface 
      functional groups. The morphology and chemical structure of the Fe(3)O(4)/Carbon 
      nanocomposites were characterized by the N(2) adsorption, Fourier transform 
      infrared spectrometer (FT-IR), X-ray diffraction (XRD), Scanning electron 
      microscope (SEM), Transmission electron microscope (TEM) and Vibrating sample 
      magnetometer (VSM). Batch adsorption experiments were performed and showed 
      significant removal efficiency of 90% at the first ten minutes for Fe(3)O(4)/AC 
      nanocomposite. Analysis of adsorption equilibrium revealed that AC/Fe(3)O(4) is well 
      fitted with Langmuir model, a homogeneous adsorption having an adsorption 
      capacity of 270 mg/g. The GO/Fe(3)O(4) can fit with both Langmuir and Freundlich 
      models indicating multilayer adsorption on the surface of the adsorbent with an 
      adsorption capacity of 81.9 mg/g. In the case of adsorption kinetics, both 
      adsorbents follow the pseudo second order kinetics model showing high F?(2) values. 
      Both adsorbents demonstrated advantageous superparamagnetic properties for their 
      easy recovery from aqueous solutions and prospective applications to toxic 
      removal in water and wastewater.
