Abstract: “In order to develop water treatment performance, graphene oxide based inverse spinel nickel ferrites (GONF) and reduced graphene oxide based inverse spinel nickel ferrites (rGONF) nanocomposites were prepared using graphene oxide (GO) and inverse spinel nickel ferrite (NiFe2O4) by thermal precipitation method. The interface interactions of GO and NiFe2O4 were studied. The X-ray diffraction spectrometer (XRD), and Fourier-transform infrared spectroscopy (FT-IR) and BET studies showed that the formation GONF and rGONF. Scanning electron microscopy (SEM) studies observed porous surface morphology of GONF and rGONF. The magnetic studies revealed that the ferromagnetic property of GONF and rGONF, but the later one shows less Ferro magnetic intensity than GONF. It was well performed for the adsorption removal As(V) and subsequently easy magnetic separation from water. The sorption studies revealed that the sorption was rate-limiting pseudo -second-order kinetics with mono layer chimisorption”
