Description
Graphene oxide (GO) and two magnetic graphene oxide (MGO) composites with a different amount of magnetite were synthesized, characterized and used in sorption experiments. The effect of pH on sorption of Am(III) and Pu(IV) isotopes as well as Co(II), Ni(II), Cu(II) and Pb(II) to GO and MGO was studied in equilibrium and kinetic experiments. The adsorption capacities varied from 30 to 574 mg g-1 while rate constants ranged from 0.29 to 0.46 min-1 and increased in the following order Co, Cu, Pb and Ni. Large variations in the uptake of studied elements by adsorbents depending on initial and final pH of solutions were observed. (author)
