Abstract
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 AmIII and PuIV isotopes as well as CoII NiII CuII and PbII 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 029 to 046 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
