Scholarcy highlights

  • We show the efficacy of graphene oxide for rapid removal of some of the most toxic and radioactive long-lived human-made radionuclides from contaminated water, even from acidic solutions
  • Cation/GO coagulation occurs with the formation of nanoparticle aggregates of GO sheets, facilitating their removal
  • GO is far more effective in removal of transuranium elements from simulated nuclear waste solutions than other routinely used sorbents such as bentonite clays and activated carbon. These results point toward a simple methodology to mollify the severity of nuclear waste contamination, thereby leading to effective measures for environmental remediation
