▎ 摘 要
Graphene oxide nanoribbons (GONRs) were fabricated by chemically unzipping multiwalled carbon canotubes and were characterized by SEM, TEM, XRD, Raman spectroscopy, FT-IR, TGA and XPS. The prepared GONRs were investigated as adsorbents for the removal of U(VI) ions from aqueous solutions as a function of pH, ionic strength, contact time and temperature. The maximum sorption capacity of U(VI) on GONRs was 394.1 mg g(-1), which was much higher than some other carbon-based nanomaterials. The results show that GONRs are promising materials for the removal and enrichment of uranium from large volumes of aqueous solutions.
