“…5, the natural halloysite is comprised of Al, Si and O and Al/Si molar ratio is about 0.90:1, lower than theoretical value (1:1), which is mainly due to an aluminum oxide layer located on inner of halloysite nanotube [36]. It is a reminder that EDS can hardly scan to test the elements of dye molecules which completely entered into the interior of halloysite nanotubes [24,36]. The Al/Si ratio of the blank sample almost unchanged, indicating that the solvent water has no influence on the halloysite during adsorption.…”

“…This could be explained by a difference in binding mechanism of halloysite to the anionic dyes and a strong interaction between CR and HNT. 41 In addition, the formation of inclusion complexes between CR and β-CD occurs. 42 At lower pH, the sulfonate ions of CR can be neutralized, and the complexing effect between neutral CR and the cavity of β-CD is strengthened, thereby promoting adsorption of CR.…”

Inorganic−organic nanosponge hybrids based on halloysite clay and organic cyclodextrin derivatives (HNT-CDs) were developed by means of microwave irradiations in solvent-free conditions. The HNT-CDs nanomaterials characterized by FT-IR, TGA, BET, TEM, SEM, DLS, and ζ-potential have showed a hyper-reticulated network which possesses both HNT and cyclodextrin peculiarities. The new HNT-CDs nanosponge hybrids were employed as nanoadsorbents, first choosing Rhodamine B as the dye model, and furthermore for the removal of some cationic and anionic dyes, under different pH values (1.0, 4.54, and 7.4). The collected results showed that the pH solution as well as the electrostatic interactions affect the adsorption process. Factors controlling the adsorption process were discussed. The experimental adsorption equilibrium and kinetic data were best described by the Freundlich isotherm model. Excellent adsorption efficiency for cationic dyes were observed with respect to anionic ones. The results suggest that HNT-CDs nanosponge hybrids are a good nanoadsorbent for selective adsorption of cationic dyes with respect to the anionic ones from aqueous solutions.

“…The wastewater from Raze paint industry is one of the sewage that is not easy to clean. These wastewaters contain significant amounts of organic dyes [11][12][13] . The presence of organic dyestuffs in industrial wastewater, due to the prevention of light penetration into the water, disrupting the photosynthesis process, reducing the oxygen transfer to inside the water and the solubility of the gases and their toxic effects, they cause irreparable damage to the environment.…”

In this study, the synthesized is nanocomposite (CAU-10-H) all samples were characterized by Scanning electron microscope (SEM), Transmission electron microscopy (TEM), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR). The (nanofiltration (NF)) membranes were constructed by interfacial polymerization of 1, 3, 5-benzenetricarbonyl trichloride and Piperazine using different loading of (CAU-10-H) (0.250, 0.50% wt.). The removal of color from the water by membranes with Solution filtration showed that the membrane containing 0.50% wt. of the nanocomposite (CAU-10-H) had the best. The removal of color from the water flux rejection of the thin-film nanocomposite (TFN) membrane which the removal of color from the water flux was 25.45 L/m2.hr and Tirmethylcyclohexan-1-one rejection was 99.35% at 6 bar.
