Correction: Removal of Cu(II) and Fulvic Acid by Graphene Oxide Nanosheets Decorated with Fe3O4 Nanoparticles (ACS Appl. Mater. Interfaces (2012) 4:9 (4991−5000) DOI: 10.1021/am301358b)

Abstract

Page 4992. It has come to our attention that the original Figure 1A was the SEM image of rGO/Fe3O4 and not GO/Fe3O4 because of improper sample characterization. In addition, the XRD pattern of GO/Fe3O4 (Figure 1C) and the magnetization curve of GO/Fe3O4 (below inset being separation of particles of GO/Fe3O4 by a magnet; Figure 1F), the Raman spectrum of GO/Fe3O4 (Figure S2E), and the behavior of GO/Fe3O4 loaded with adsorbate in a magnetic field under different conditions (Figure S3) in the original Supporting Information were also incorrect because erroneous data were used during the figure preparation. Accordingly, corrected parts A, C, and F are given here in the revised Figure 1. {figure presented}. Page 4993. In the text discussion of Figure 1C, the original sentence should be changed to the following: "The intense diffraction peaks indexed to (220), (311), (400), (422), (511), and (440) planes appearing at 2θ = 30.15°, 35.69°, 43.32°, 53.89°, 57.13°, and 62.87°, respectively, are consistent with the standard XRD data for the cubic phase Fe3O4 with a facecentered cubic (fcc) structure (JCPDS No. 89-3854)." Page 4999. The new Supporting Information is given here with the corrected Figures S2E and S3 and replaces the original Supporting Information that is associated with the published paper. These corrections do not affect any of the major conclusions of the paper. (Figure Presented).
