Comments concerning papers about cationic dyes sorption, published by Saeed et al. (2023), Tan et al. (2023) and Yıldız et al. (2023)

Abstract

ABSTRACT Recently, the three independent papers cited in the title were published in this journal, dealing with the sorption of cationic dyes on specially prepared solid sorbents. Although kinetics, isotherm and thermodynamics are three important components for the correct description of any sorption process, the authors of these original papers introduced several fundamental errors in these parts. Therefore, we present detailed analyses of these errors in the hope that this “Comment” paper will also be useful to other researchers (especially early career researchers) to avoid replicating such errors elsewhere in the future.
