“…Among the various techniques, adsorption appeared to be an attractive and acceptable approach for the removal of dyes due to its low cost, ease of handling, high efficiency and no threat of secondary contamination [5][6][7]. The common adsorbents used for dyes removal primarily included oxidized multiwalled carbon nanotubes [8][9][10], graphene oxide (GO) [11][12][13][14], biomass sources [15][16][17], activated carbons [18][19][20], and so on. However, efforts would be still needed for the development of new potentials and effective adsorbents.…”
