In this study As(V) removal was done by GO and fRGO and a comparative study was made. At equilibrium pH (pH 6) fRGO gives more As(V) removal than GO. For both the materials, Langmuir adsorption isotherm fit better than Freundlich isotherm. The adsorption capacities of GO and fRGO are determined (12.04 mg/g) and (28.57 mg/g) respectively. Both materials follow pseudo-second order removal kinetics and fRGO (0.09 g/mg/min) shows a faster removal rate than GO (0.07 g/mg/min). It was found that fRGO can remove 2.4 times more arsenic than graphene oxide (GO).
