Abstract: Methods of sorption of various materials from an environment are disclosed herein. Embodiments of the materials include radioactive elements chlorates, perchlorates, organohalogens, and combinations thereof. Other embodiments pertain to methods of sorption of cationic radionuclides. Compositions produced by such methods are also disclosed herein. Embodiments of the methods may include contacting graphene oxides with the environment and sorption of the materials to the graphene oxides. In some embodiments, the sorption is relatively rapid in comparison to known sorbents; even in the presence of relatively higher concentrations of complexing agents. In some embodiments, the methods further include separating the graphene oxides that sorbed materials from the environment. Yet other embodiments may include desorbing the materials from the graphene oxides that sorbed the materials, and compositions therefrom.
