摘要: The potential coexistence of toxic metals and graphene oxide (GO) in the natural environment threatens human health. Herein, rare earth doped titanium dioxide coated carbon sphere composites (C@ La-TiO2 and C@ Ce-TiO2) were synthesized for the simultaneous removal of GO and Cr (VI) from wastewater. The results showed that a relatively high concentration of NaCl was beneficial to the binding of GO, whereas it was adverse to Cr (VI) removal. The removal capacity of C@ La-TiO2 reached 383.3 mg/g for GO …
