“…Also, they are abundantly available at lower cost in compare to other high cost adsorbents such as commercial activated carbon. Natural clays are usually used for the removal of cationic dyes such as methylene blue due to their natural negative charged; however modifications to the surface of clay using surfactants can change the surface charge of clay from negative to positive [24]. These modifications enhance the adsorption of anionic dyes.…”

“…These modifications enhance the adsorption of anionic dyes. Researchers studied various type of clays in the removal of textile dyes and metal ions such as Reactive red 120 by raw clay [24], Brilliant green dye by red clay [56], Congo red by sodium bentonite, kaolin and zeolite [57], zinc ions by kaolin [55] and Methylene blue by montmorillonite clay [58]. Readers are encourage to go through a review article reported by Yagub et al, (2014) [8].…”

“…Therefore, in the past few years, there is a growing need to find low-cost, locally available, effective adsorbent for the removal of dyes. The extensive research has been undertaken to study the application of a number of natural resources including solid wastes such as natural and synthetic clay, as dye adsorbents have attracted interests [4][5].…”

“…Currently, a number of studies have reported on the use of many natural materials such as zeolites [5,6], clays [7][8][9], coal [10,11] and plant biomass [12][13][14][15][16] for decolorization of dye-containing effluents. These have been classified as low-cost sorbents since their initial cost is very low and they are locally available materials [17].…”
