“…As seen from these XRD patterns, the modifiers replaced the place of DMSO at the end of replacement reaction of kaolinite nanoclay intercalated with DMSO and hydrogen bonds existed between kaolinite nanoclay and the modifiers. The new peaks at 25.545, 23.198, and 20.790 Å were appeared at the end of substitution reaction and the peak of kaolinite-DMSO, which exists at 11.232 Å, was disappeared as the result of the substitution of GA with DMSO [23]. Elbokl and Detellier (2008) studied the intercalation reaction of cyclic imides with kaolinite and they reacted SIM and GA with kaolinite intercalated with DMSO.…”

The aims of the present study were to synthesize the intercalated kaolinite samples with dimethylsulfoxide (DMSO), glutamic acid (GA), succinimide (SIM), cetylpyridiniumchloride (CPC), and hexadecyltrimethylammoniumchloride (HDTMA+); to characterize by X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy-attenuated total reflectance (FTIR-ATR), and to determine the hemocompatibility and the cytotoxic effects of the intercalated kaolinite nanoclays on human lymphocytes. It was found that the intercalation with DMSO did not cause any decrease in cell viability until its maximum concentration (500 µg/mL), however, the intercalation with SIM, CPC, and (HDTMA+) causd important decreases in lymphocyte viabilities. It was determined that no significant decrease was observed in protein content of the lymphocyte cells exposed to the kaolinite nanoclays except the ones intercalated with SIM. Furthermore, the pristine kaolinite nanoclays which were intercalated with DMSO, GA, and SIM exhibited high hemocompatibility and the nanoclays intercalated with CPC and (HDTMA+) were highly hemocompatibile for the amounts below 125 and 500 µg/mL, respectively. All the results of this work can serve for the human risk assesment of intercalated nanoclays.

“…The intercalation of kaolinite was born in 1960 and since that time until now, the industrial uses of intercalated kaolinite continues to grow. This growth is directly linked to its reactivity and these surface properties, which are remarkably improved after modification [13]. Kaolinite has been intercalated by several polar compounds such as: N-methyl formamide [14], urea [15], potassium acetate [16][17][18], hydrazine hydrate [19] and dimethyl sulfoxyde [20,21].…”

Tamazert kaolin was modified with dimethyl sulfoxide (DMSO). The starting material and resulting from the intercalation were characterized by X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron microscopy (SEM). Intercalation caused considerable changes in our clay by increasing the basal spacing to 11.22 Å, an intercalation rate of 98 %. The adsorption of methylene blue was studied as a function of pH, contact time, temperature, dye concentrations and adsorbents. Kinetic data have been adequately described by the pseudo-second order and intraparticle scattering model. The adsorption isotherm is in good agreement with the Redlich-Peterson model. A change in thermodynamic values (ΔH°, ΔS° and ΔG°) was observed after intercalation. Adsorption became non-spontaneous exothermic and ordered.
