Correction: Plasma-induced grafting of polyacrylamide on graphene oxide nanosheets for simultaneous removal of radionuclides

Abstract

Correction for ‘Plasma-induced grafting of polyacrylamide on graphene oxide nanosheets for simultaneous removal of radionuclides’ by Wencheng Song et al., Phys. Chem. Chem. Phys., 2015, 17, 398–406.

The authors regret that the Raman in Fig. 2c and XRD in Fig. 2e of the above mentioned paper were incorrect because of confusion with other samples. Besides, the labels of the XPS N 1s spectra of PAM/GO and PAM/GO-Eu were mislabeled in Fig. 7b, and the XPS N 1s spectra of PAM/GO was reanalyzed (Table S6). Thus, the Raman of GO and GO/PAM, XRD of PAM/GO and high-resolution XPS N 1s spectra of PAM/GO and PAM/GO-Eu were corrected below. The correction has no effect to the discussion and main conclusion.
