Retraction notice to “Controlled synthesis of porous Zn/Fe based layered double hydroxides: Synthesis mechanism, and ciprofloxacin adsorption” [Sep. Purif. Technol. 278 (2022) 119481] (Separation and Purification Technology (2021) 278, (S1383586621011898), (10.1016/j.seppur.2021.119481))

This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy). This article has been retracted at the request of the Editor-in-Chief. Following a complaint from a reader, the editors have expressed concerns regarding the following images: Figure 2(a) (XRD), Figure 4(a) (XPS), Figure S2 (XRD), and Figure S3 (XPS), which appear to have been manipulated e.g. some of the peaks in the XPS have been truncated; repetitive background noise patterns in XRD data. The manipulation of images and data in this way is a serious offense to the integrity of the scientific community and casts doubts on all the data, and accordingly also the conclusions based on that data, in this publication. Apologies are offered to readers of the journal that this was not detected during the submission process.
