RETRACTED: Preparation of magnetic mesoporous poly-melamine-formaldehyde composite for efficient extraction of chlorophenols

This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal). This article has been retracted at the request of the authors and the Editor-in-Chief. The article reports the synthesis of basically the same adsorbent as reported by the authors in another publication published in Microchimica Acta, 185 (2018) 19 https://doi.org/10.1007/s00604-017-2593-5. Although the adsorbent material was used to enrich different analytes in the two papers, the description about the preparation of the material is similar in both papers and figures 2C, 3B and 3C in the Talanta paper obtained from the material characterization are identical to Figures 1C, 2A, and 2B in the Microchimica Acta paper. Both publications do not refer to each other. One of the conditions of submission of a paper for publication is that authors declare explicitly that the paper is not under consideration for publication elsewhere. As such this article represents a severe abuse of the scientific publishing system. The scientific community takes a very strong view on this matter and apologies are offered to readers of the journal that this was not detected during the submission process
