Two sources of cellulose used to fabricate graphene oxide-cellulose based aerogels were cellulose nanocrystals (CNC) and rice straw. Up to now, aerogels obtained from graphene oxide and cellulose in rice straw remain rare. In this report, aerogel materials show a strong ability that can be used in water treatment by adhering to a simple, green procedure. Scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR), thermal gravimetric analysis (TGA), nitrogen physisorption isotherm were used to examine the shape, features, and physico-chemical properties of these aerogels. The aerogels exhibited high porosity (97.14-98.53 %) and low density (0.0197-0.0385 g/cm3). In adsorption experiments, they showed a great capability in adsorption of Cu2+ (98.73-123.2 mg/g), of various oil types (up to 28.11 g/g) and of methylene blue (MB) (up to 96.23 %).
