Perhydroxy-CB[6] decorated graphene oxide composite for uranium(VI) removal

We report the synthesis of perhydroxy-cucurbit[6]uril decorated graphene oxide composite [denoted as HO-CB[6]/graphene oxide (GO)] through a self-assembly process in dimethyl sulfoxide solvent. The obtained composite was characterized by transmission electron microscopy, thermogravimetric and differential temperature analysis, fourier transformed infrared spectroscopy, and XRD. HO-CB[6]/GO was used as an adsorbent for the removal of uranium(VI) from aqueous solution. The results showed that HO-CB[6]/GO exhibited a fast sedimentation velocity and a high adsorption capacity to uranium(VI). HO-CB[6]/GO could be a promising candidate as sorbent for uranium-bearing wastewater treatment.
