Removing dye pollutants from industrial waste water is a common environmental application of nanomaterials. This study investigated in-situ synthesis and adsorbing ability of a magnetic nanocomposite based on graphene for both cationic and anionic dyes. To determine composite structure, chemical bonds, morphological and magnetic features X-ray diffraction XRD, Fourier transform of infrared spectroscopy FTIR, Field Emission Scanning Electron Microscopy FESEM and Vibrating-sample magnetometer VSM were examined and adsorbent capacity function of solution pH, time of removal and material content for Methyl Orange MO, Methylene Blue MB, Crystal Violet CV and Rhodamine B RhB by two method Isotherm Langmuir and Isotherm Freundlich were studied. Experimental results of Iron-Graphene nanocomposite showed average removal adsorbent of 70 in 30 minutes and removing by external magnetic field in a minute. This study shows that the synthesized magnetic nanocomposite advances for high amount of pollutant cleaning in a short time by using small amount of materials.
