“…(Ma, 2010). A number of studies have demonstrated that the QAC-modified PILC, also named 'inorgano-organo clays', have an appreciably higher capacity for adsorbing organic contaminants than their unmodified counterparts (Bouberka et al, 2005(Bouberka et al, , 2009Tahani et al, 1999a;Zhu et al, 2009a). These materials are also effective in taking up both the organic and inorganic contaminants simultaneously (Zhu et al, 2009a).…”

“…Inorgano-organo clays may be synthesized by three different methods: (1) intercalation of the metal hydr(oxide) polycation into swelling clay minerals (to form PILC), followed by the QAC of choice to modify the PILC (Bergaya et al, 2005); (2) mixing the polycation and QAC, and intercalating the mixture into the clay mineral; and (3) intercalation of the QAC (to form an OC), followed by that of the polycation (Bouberka et al, 2009;Zhu et al, 2009b).…”

“…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.…”

Cr-pillared interlayered clays (Cr-PILCs) have been prepared from natural calcium bentonite originating from a Romanian deposit and the effect of some parameters on the chemical and textural properties have been investigated. The crude bentonite and the derived materials were characterized by nitrogen adsorption-desorption technique, X-ray diffraction, scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy and transmission electron microscopy. The specific surface area values, the pore size distribution, morphological characteristics and the basal spacing of the Cr-PILCs are strongly affected by the process parameters. The influence of three relevant factors (metal/clay ratio, calcination temperature and calcination duration) on the specific surface areas of the Romanian Cr-PILCs was investigated using a 3 3 factorial design methodology. The optimum conditions to obtain CrPILCs with a specific surface area of 183 m 2 /g (more than four times higher than the raw material) were as follows: metal/clay ratio of 10 mmols/g, calcination temperature 300°C and calcination duration 60 min. The model developed in this paper predicts very well the experimental results. Due to the high porosity and adsorption properties, the prepared Cr-PILCs have great potential in remediation of industrial liquid effluents.

“…A recent development of great interest is the preparation of surfactantmodified pillared interlayered clays (PILC) (Tahani et al, 1999;Annabi-Bergaya, 2008;Zhu et al, 2009a;He et al, 2014;Ma et al, 2014aMa et al, , 2014b. Having both hydrophilic and hydrophobic surface properties, these inorganic-organic clays (IOC) are potentially capable of synchronically removing organic and inorganic contaminants in wastewater (Zhu and Zhu, 2007;Bouberka et al, 2009;Zhu et al, 2009b;Ouellet-Plamondon et al, 2012).…”
