Retraction: Mutual effect of Cs(i) and Sr(ii) sorption on nano-talc investigated by EXAFS, modeling and theoretical calculations (Environ. Sci.: Nano (2019) 6 (672–683) DOI: 10.1039/C8EN01279B)

The Royal Society of Chemistry, with the agreement of the named authors, hereby wholly retracts this Environmental Science: Nano article due to concerns with the reliability of the data in the published article. The EXAFS data in Fig. 3 are unreliable given that the three spectra presented in Fig. 3B have been duplicated in the region R?A) > 5.1. Given the significance of the concerns about the validity of the data, the findings presented in this paper are no longer reliable. Signed: Yubing Sun, Tasawar Hayat, Yuejie Ai, Virender K.
