The characterization of organo-montmorillonite modified with a novel aromatic-containing gemini surfactant and its comparative adsorption for 2-naphthol and phenol

A facile strategy for preparing Gemini surfactant‐modified montmorillonite and its effect on the morphology and mechanical properties of polyethylene/polystyrene

“…The space of Gemini C 18 ‐MMT was increased to 1.77 from 1.24 nm of Na‐MMT appeared at 5.00°. The intense peak of Gemini C 10 ‐MMT and Gemini C 18 ‐MMT at 1.77 nm, 1.74 nm with a shoulder at 1.17 and 1.16 nm that represents as a paraffin‐bilayer arrangement with lateral bilayer, suggesting that the Gemini surfactant can enlarge the basal space more efficiently . All of the peaks have shown that Gemini surfactant can increase the lamellar space of the Na‐MMT, which was consistent with the FTIR results.…”

Impact of salinity and dispersed oil on adsorption of dissolved aromatic hydrocarbons by activated carbon and organoclay

“…Preliminary batch adsorption experiments showed that equilibrium was reached within three hours, which is in agreement with several other researchers [26,13,50]. Doses of the adsorbents evaluated in this study ranged from 1 to 100 mg/L for PAC, from 100 to 10,000 mg/L for OC, and from 20 to 2000 mg/L for BTMA.…”

Comparative study of Hg(II) adsorption by thiol- and hydroxyl-containing bifunctional montmorillonite and vermiculite

“…Moreover, it is proposed that the adsorption of Hg(II) onto the clay minerals is physical process in terms of the H value which is less than 40 kJ mol −1 [22]. The positive values of S for Mt and BAL-Mt confirm an increase of arbitrariness or disorder at the solid-liquid interface during the adsorption process, while an opposite interpretation of which is suitable for the negative data of S for Vm and BAL-Vm [45,46]. The negative values of G indicate the adsorption process to be feasible and spontaneous, which is in line with the decrease of the Hg(II) uptake by these adsorbents with increasing temperature [26].…”
