Adsorption characteristics of Th(IV) ions on reduced graphene oxide from aqueous solutions

- Reduced graphene oxide was prepared using thiourea dioxide as a reducing agent.
- Reduced graphene oxide was used to remove Th4+ from aqueous solution.
- Adsorption process was controlled by the pseudo-second order kinetic model.
- The equilibrium adsorption data was well described by the Langmuir isotherm model.
- The adsorption process was feasible, spontaneous and endothermic in nature.
