Retraction notice to "Photocatalytic degradation of organic synthetic dyes and textile dyeing waste water by Al and F co-doped TiO₂ nanoparticles" [Environ. Res. 206 (2022) 112492]

This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/locate/withdrawalpolicy). This article has been retracted at the request of the Editor-in-Chief. By changing the contrast and brightness, it appears that the various EDX spectra in Figure 5 show signs of being edited at several areas and are likely to originally be the same spectrum. Furthermore, the FTIR spectrum (Figure 2) in the original version showed signs of manipulation and this was removed and replaced with other FTIR spectra in the revised/published version. The corresponding author was contacted for comment about these concerns but failed to respond. The Editors have therefore lost confidence in the reliability of the findings presented in this article as a whole, and are retracting it. Unauthorised authorship changes were made when the revised version of this paper was submitted, following suggestions for relatively minor revisions from the reviewers and Guest Editor, with authors Mansour K. Gatasheh, Ashraf Atef Hatamleh and S.Ilavenil being added to the paper. No explanation was given for this change, nor was it approved by the editor. This authorship change breaches the policies of the journal and as a result, the editors no longer have confidence in the contributions of the authors in this paper and are retracting it. The journal apologises for not having identified the problematic authorship change during the review process and for any resulting inconvenience.
