Assessment of swelling inhibitive effect of CTAB adsorption on montmorillonite in aqueous phase

Organophilic bentonites obtained by microwave heating as adsorbents for anionic dyes

“…The percentages of total mass losses between 298-1200 K were higher for organobentonites than pristine bentonite. The first mass loss associated with the desorption of interlayer water was lower for the organobentonites (<1%) than the pristine sample, which was attributed to the hydrophilic character of the samples after the organofunctionalization (Moslemizadeh et al, 2016;Santos et al, 2018). The thermal elimination of alkyl surfactants proceeded at temperatures above 473 K. The second, third, fourth and fifth events in the TG curves of the hybrids were attributed to loss of the surfactant moieties and are in agreement with the literature (Park et al, 2011;Zhu et al, 2012;Taleb et al, 2018).…”

Antimicrobial Nanocomposites Prepared from Montmorillonite/Ag+/Quaternary Ammonium Nitrate

“…arise from -CH 2 -and -CH 3 stretching vibrations, while the one at 1384 cm −1 belongs to C-H symmetric deformation vibrations [29]. This further reveals that DOHEAN has intercalated into the MMT layers.…”

Effect of a novel environmentally friendly additive of polyaspartic acid on the properties of urea formaldehyde resins/montmorillonite

“…The band at about 1030 cm −1 is due to the stretching vibration of the SiO . The bands at 525 and 466 cm −1 are attributed to the stretching vibrations of SiOAl and bending vibrations, respectively . According to Figure (e), the absorption band at approximately 3348 cm −1 is associated with NH stretching vibrations, the band at around 2964 cm −1 is ascribed to the CH stretching vibrations, and the strong band at 1640 cm −1 is assigned to the CO stretching vibration in NHCO group .…”
