Abstract:Functionalized graphene-cement-based composites (FGCC) was prepared by the Portland cement with incorporation of functionalized graphene nano-platelets (FGN), which was obtained by the oxidation of graphene nano-platelets. Compared to the conventional cement-based materials, the FGCC have not only high adsorption efficiency-removal percentage of 3d-adsorption reaching to 96% and 14-adsoprion more than 99%, but also the better recycling efficiency. The characterization results of scanning electron (SEM) microscope and energy dispersive spectrometer (EDS) shows the microstructure and of morphology FGCC and the elements distribution of heavy metals. And X-ray diffraction (XRD) determined the existing forms of heavy metal-complexes.
