“…The primary diffraction peak attributed to 001 plane for natural bentonite appeared at 2θ value of seven, and the corresponding spacing value is 1.26 nm (Figure 1a), which is near to the range commonly reported for natural bentonite (~1-1.2 nm) (Sarkar, Naidu, and Megharaj 2013). With modification of Fe and Al, the (001) diffraction peak shifts toward low angle, i.e., the d(001) spacing increased.…”

“…This pH range is also suitable for illite formation as an Al, Mg and Fe-bearing phyllosilicate clay mineral [88]. Moreover, Hg absorption into the soil is also enhanced by the presence of these clay minerals [89]. Studies from [90] indicated that trace elements such as Cr, Co, Cu, Fe, Mg, V and Ni turn to be trapped within the duricrust layer along the soil profile even though they are normally mobile in the weathering environment.…”

“…Recent works have shown that many materials such as functionalized nanomaterials, magnetic particles, functionalized silica, nanotubes, etc. [1-8, [16][17][18][19][20][21][22][23] have been used as effective adsorbents for the removal of Cu(II) or Cr 2 O 7 2À from wastewater. However, to the best of our knowledge, most of published works on these adsorbents only focus on the excellent selectivity of Cu(II) cations [1, 5,6,[20][21][22] or the perfect extraction of Cr 2 O 7 2À metalloid anions [2][3][4][16][17][18][19].…”
