RETRACTED: Kinetic and adsorption mechanism of Cu(II) and Pb(II) on prepared nanoparticle layered double hydroxide intercalated with EDTA

This article has been removed at the request of the Editor-in-Chief. Please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).Reason: This article has been retracted at the request of the Editor-in-Chief as two figures and various parts of the text are a duplicate of a paper that has already been published in (Uptake of Cu2+, Cd2+ and Pb2+ on Zn-Al layered double hydroxide intercalated with edta, by M.R. Pérez, I. Pavlovic, C. Barriga, J. Cornejo, M.C. Hermosín, M.A. Ulibarri, Appl. Clay Sci. 32 (2006) 245-251, doi: 10.1016/j.clay.2006.01.008). One of the conditions of submission of a paper for publication is that authors declare explicitly that the paper is not under consideration for publication elsewhere. As such this article represents a severe abuse of the scientific publishing system. The scientific community takes a very strong view on this matter and we apologize to readers of the journal that this was not detected during the submission process.
