Corrigendum: Nanoscale Zero-Valent Iron Particles Supported on Reduced Graphene Oxides Using a Plasma Technique and Their Application for Removal of Heavy-Metal Ions.

Abstract

The authors regret errors in Figure 2, Figure 3a, Figure 3b and Figure 8c in the published article. The sample information was incorrect due to replication errors in the PPT software and an inadvertent mistake of data import when plotting. The corrected Figure 1, Figure 2a, Figure 3b and Figure 3c are shown below. The corrections do not affect the main discussion and conclusions of the original article. TEM images of A) NZVI, B) NZVI/rGOs (1 : 1), C) NZVI/rGOs (1 : 4), and D) NZVI/rGOs (1 : 5). HRTEM images of E) NZVI, F) NZVI/rGOs (1 : 1), G) NZVI/rGOs (1 : 4), and H) NZVI/rGOs (1 : 5). a) XRD patterns of NZVI/rGOs (1 : 4), NZVI, and rGOs. b) High-resolution spectra of Fe 2p for NZVI and NZVI/rGOs (1 : 4). XPS analysis of NZVI, rGOs, and NZVI/rGOs (1 : 4) after chromium removal for 2 h: high-resolution spectra of Fe 2p for NZVI and NZVI/rGOs before (C) and after chromium removal (D; m/V=0.1 g L−1, CCrVI=100.0 mg L−1 and pH=5.0). The authors would like to apologise for any inconvenience caused.
