| Abstract: | A functional graphene oxide nanoribbons/manganese dioxide composite material (MnO2-GONRs) was synthesized by hydrothermal method using graphene oxide nanoribbons (GONRs) as raw material which were formed by longitudinal unzipping of multi-walled carbon nanotubes with KMnO4 and H2SO4. The microstructure of MnO2-GONRs was characterized by SEM and FT-IR. The various factors affecting the adsorption of Th(IV) in aqueous solution such as pH, solid–liquid ratio, contact time, initial concentration and temperature were investigated by batch static adsorption experiments, and the adsorption mechanism is also discussed. The results showed that MnO2-GONRs had a good adsorption effect on Th(IV) with a maximum adsorption of 166.11 mg/g. |
