摘要：
Exfoliated graphitic nanoplatelets (xGnP) show adsorption capability and adsorption efficiency for lead removal from water, the adsorption being influenced by the pH value of the solution and the xGnP surface characteristics, which are controlled by their treatment processing. In this work, oxidized exfoliated graphite nanoplatelets entrapped in chitosan/THF adsorptive materials on nylon discs are used as improved adsorbents for Pb(II) removal from aqueous solutions. Preliminary results are presented in terms of sorption capacity, kinetics and reuse.
