Abstract

In the present study magnetite (Fe3O4) decorated graphene composite (Fe3O4@rGO) material was synthesized using Aloe vera plant extract via the solvothermal route. The prepared Nanocomposite was studied as a magnetic adsorbent for the removal of Cr(VI) ions from water. The physicochemical characterization of the synthesized composite was performed with the help of FESEM, FTIR, TEM, magnetic hysteresis analysis (MHA) and XRD. The maximum adsorption capacity for Cr(VI) ions by nanocomposite was investigated in batch modes. The kinetic and isotherm models were tested to understand the adsorption process. Synthesized nanocomposites resulted with significant adsorption potential for the Cr(VI) ion which can be further exploited at pilot scale for the removal of metal ions from the polluted water.
