摘要:A simple route is presented for the fabrication of a magnetic beta-cyclodextrin/graphene oxide nanocomposite (MCGN). The characteristic results of FTIR, SEM, TEM, VSM and XRD showed that MCGN was prepared. The large saturation magnetization (50.13 emu g(-1)) of the synthesized nanoparticles allows fast separation of the MCGN from liquid suspension. The MCGN demonstrates extremely fast Cr-removal from wastewater with a high removal efficiency within 60 min. The adsorption kinetic data were best described by a pseudo-second-order model. The Cr-removal capability is more than 120 mg g(-1), which is much higher than the previously reported values of other nanomaterials, as Cr-removal adsorbents. The MCGN was stable and easily recovered. The adsorption isotherms were investigated, and indicate that the equilibrium adsorptions are well-described by the Langmuir isotherm mode. The MCGN could be a good candidate for efficient Cr-removal from wastewater and for the deep-purification of polluted water.
