Abstract

• The graphene shells ere prepared to apply as the electrosorbent for the electrosorption. irstly, graphene oxide as collected to determine sorption activities of irconium and iron. The solubility dispersion in ater of graphene oxide as studied. nd then, the interaction of irconyl chloride solution ith the graphene oxide as also determined. Moreover, the sorption of iron ith graphene oxide gave the magnetic sorbent. The hollo nanosphere graphene shells ith the thicness of nm ere obtained by the methane pyrolysis on spherical i particles. The electrosorption of a ions aCl aqueous solution as carried out on the nanosphere carbon shells electrodes. The electrosorption of r ions rCl aqueous solution . . mgg on the graphene electrodes as also determined. rom the experimental results the maximum sorption capacity as r . mgg on graphene electrode
