Exfoliated graphitic nanoplatelets (xGnPs) show adsorption capability and adsorption efficiency for lead removal from water, the adsorption being influenced by the solution pH value and the xGnPs surface characteristics, which are controlled by their treatment processing. The adsorption isotherms were described by both Langmuir and Freundlich models. These results suggest that xGnPs are remarkable lead adsorbents, having potential applications in environmental protection. (C) 2010 Elsevier B.V. All rights reserved.
