چکیده انگلیسی
Independent GO nanosheets are observed through TEM micrographs and it was clear that the addition of GO to the composites increases folding, roughness and groves that what would lead to increasing the surface area and consequently enhancing the adsorption capacities of the composites. The FTIR spectra of GOBC proved that there is a chemical interaction between GO and the cellulose chains via hydrogen bonding. The XRD pattern of graphite and GO revealed that the original graphite powders had almost been completely oxidized and GO has been exfoliated successfully. The analysis of kinetic models showed that the pseudo-first-order adsorption mechanism is predominant for GOCB and the rate-limiting step was physisorption in nature, where intraparticle diffusion is the rate-controlling mechanism.
