Paper-like composites of cellulose acetate–organo-montmorillonite for removal of hazardous anionic dye in water

Optimization of the adsorption of a textile dye onto nanoclay using a central composite design

“…However, it can cause lowering of the concentration gradient between the adsorbent interface and the solution at constant adsorbate concentration, resulting in a small decrease in the adsorption at higher adsorbent concentrations. 41,42 Similar behavior was observed and reported by Silva et al. in their study on the adsorption of an industrial anionic dye by modified montmorillonite.…”

“…In contrast, Zhou et al reported that dye adsorption onto cellulose acetate/organo-montmorillonite composites is temperature-dependent in which the increase in the temperature resulted in an increment in the adsorption. 41 The interactive effect of the temperature and adsorbent dosage on BY2 removal (%) is shown in …”

Effect of the Organobentonite Filler on Structure and Properties of Composites Based on Hydroxyethyl Cellulose

“…Modification of bentonite by the HDTMA-Cl particles results in displacement of the reflection (001) towards 2 = 4.14 ∘ (Figure 6(b)) and increase in the interplanar distance from 1.26 to 2.13 nm (Table 3). This conclusion is consistent with the data of [22,35] in which the montmorillonite clays modified with quaternary ammonium salts were researched.…”

Synthesis of cationic chitosan hydrogel and its controlled glucose-responsive drug release behavior

“…A strong peak at 1483 cm À1 of HTCC corresponded to the C-H bending of trimethylammonium group, confirming the existence of the quaternary ammonium salt [17][18][19]. It should be also noted that the peak corresponding to the primary amine (1600 cm À1 ) of chitosan disappeared gradually and a new peak at around 1633 cm À1 for HTCC was recorded, revealing the change of the primary amine to the secondary amine structure due to the reactions at -NH 2 sites on the chitosan backbones.…”
