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.

“…Many different pillaring polyhydroxocations (Al, Zr, Fe, Cr, Ti, Cu, Ni [9][10][11][12][13][14][15][17][18][19][20][21][22][23]) have been reported in the literature, but only the Al-polyhydroxocation has been well defined for its chemical structure and composition [9]. AlPILCs were the first prepared and the most extensively studied.…”
