Retraction notice to “Enhancing the removal of organic and inorganic selenium ions using an exfoliated kaolinite/cellulose fibres nanocomposite”(Carbohydrate Polymers, (2021), 252, C, (117163), (S0144861720313369), 10.1016/j.carbpol.2020.117163)

This article has been retracted: please see Elsevier policy on Article Correction, Retraction and Removal (https://www.elsevier.com/about/policies-and-standards/article-withdrawal). This article has been retracted at the request of the Editors-in-Chief. Following a correction request submitted by the authors, a post-publication investigation was conducted. The investigation identified issues related to the reuse of Fig. 2 from previously published work without explicit attribution, as well as unusual authorship changes during the revision process. The authors responded promptly and offered to replace the questioned figures with new, original images generated from the same experimental work. However, the Editors-in-Chief concluded that these measures were not sufficient to fully resolve the concerns and restore confidence in the published version of the article. Therefore, they decided that retraction was necessary to preserve the integrity of the scholarly record.
