Synthesis of graphene oxide decorated with magnetic cyclodextrin for fast chromium removal
Abstract
A simple route is presented for the fabrication of a magnetic β-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.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
