In the article titled “Study of Modern Nano Enhanced Techniques for Removal of Dyes and Metals” [1], the figures except Figure 1 were reused from other published articles. They were cited, but reuse was not explicitly indicated in the text or figure legends. In addition, the article was found to contain text from published work, some without citation.
The sources for the figures are as follows:
Figures 2, 3, and 4 from Cao et al. (2011) [2] (cited as reference 58), Figure 5 from Han et al. (2013) [3] (cited as reference 62), Figures 6, 7, and 8 from Johnson et al. (2013) [4] (cited as reference 29), Figures 9, 10, and 11 from Peng et al. (2010) [5] (cited as reference 109), Figures 12 and 13 from Niu et al. (2005) [6] (cited as reference 97), and Figures 14 and 15 from Antonopoulou et al. (2012) [7] (cited as reference 38).
