摘要：

A promising strategy for clean water production is presented based on cellulose and GO. An indispensable modification of cellulose was done to increase its surface area and reactivity. Dicarboxylic cellulose (DCC) was synthesized via sodium periodate and sodium chlorite oxidation. Graphene oxide (GO) is prepared by modified Hummer's method. DCC/GO foam is fabricated in presence of ethylenediamine as a crosslinker through lyophilization process. Chemical structure and surface morphology of GO, DCC and DCC/GO foam are investigated by infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermal gravimetric analysis (TGA) and scanning electron microscope (SEM). Additionally, oil adsorption capacity of the prepared foams with different ratios of GO is studied and demonstrated a high adsorption capacity 2600% g/g.
