摘要：Well defined graphene oxide (GO) nanosheets were synthesized via a facile synthetic method and further functionalized by silanization treatment. Adsorption property of GO toward heavy metal ions was evaluated by using Pb(II) ions as model ions. The results showed that modified GO exhibit high adsorption ability for Pb(II) ion in aqueous solution and the removal efficiency is nearly 99.5%, which indicating modified GO-based carbon nanostructures provide a promising class of adsorbents for heavy metal removal.
