“…Possessing both hydrophilic and hydrophobic surfaces as well as a large porosity and surface area, these materials are potentially useful as adsorbents of volatile organic compounds (VOC) as well as of organic and inorganic contaminants in waste water (Bouberka et al, 2009;Ouellet-Plamondon et al, 2012;Zhu et al, 2007Zhu et al, , 2009a.…”

“…Therefore, developing novel adsorbents that can efficiently remove both organic and inorganic contaminants is urgent. Inorganic-organic montmorillonites (IOMts), obtained by intercalating cationic metal complexes and organic cations, are capable of removing a wide range of inorganic and organic contaminants (Zhu and Zhu, 2007;Zhu et al, 2009b;Li and Wu, 2010;Ouellet-Plamondon et al, 2012). IOMt can also serve as novel adsorbents of volatile organic compounds (Zhu et al, 2007a), and as catalysts in the degradation of adsorbed organic compounds .…”

“…So to reduce wastewater treatment cost, it is desirable to develop adsorbents that can simultaneously remove both organic and inorganic contaminants. Previous studies used both metal complex cations and organic cations as intercalators to modify the montmorillonites, and obtained inorganicorganic montmorillonites (IOMts) [24,25]. The IOMts are of the adsorption sites/domains for both organic and inorganic contaminants, and used as an effective adsorbent for the both organic and inorganic pollutants from wastewater [11,[25][26][27].…”

For combining the properties of organoclays and pillared clays, inorganic-organic clays have attracted much attention in recent years. In this study, Al Keggin cation pillared montmorillonites (Al-Mts) were first prepared and parts of Al-Mts were calcined at different temperatures (C-Al-Mts). The inorganic-organic montmorillonites were synthesized by intercalating Al-Mts and C-Al-Mts with the cationic surfactant, hexadecyltrimethyl ammonium bromide (HDTMAB). The products were characterized by X-ray diffraction, X-ray fluorescence, and simultaneous thermogravimetric analysis. For HDTMAB-modified uncalcined Al Keggin cation pillared montmorillonites (H-Al-Mts), the basal spacing increased with the increment of surfactant loading level, but the Al content of H-Al-Mts decreased simultaneously, indicating that the intercalated surfactant replaced some Al Keggin cations in the interlayer space. However, in the case of C-Al-Mts, the interlayer spaces could not be further expanded after surfactant modification, implying that the neighboring montmorillonite layers were ''locked'' by the aluminum pillars which were formed by dehydroxylation of Al Keggin cation pillars during thermal treatment. The thermal stability of HDTMAB-modified C-Al-Mts (H-C-Al-Mts) was much better than that of H-AlMts. The major mass loss of H-C-Al-Mts occurred at ca. 410°C, corresponding to decomposition of intercalated surfactant cations. In contrast, H-Al-Mts displayed two mass loss temperatures at ca. 270 and 410°C, corresponding to the evaporation of surfactant molecules and the decomposition of surfactant cations in the interlayer space, respectively.
