- W3129816361 abstract "Abstract The study describes the chemical–mineralogical characterization of Barremian sand deposits. These Sidi Aich sands were collected in central Tunisia. The collected raw silica sand from the Jebel Meloussi (central Tunisia) was characterised by different techniques, such as X-ray diffraction (XRD), X-ray fluorescence (XRF) and scanning electron microscopy (SEM). X-ray diffraction showed a predominance of quartz and potassic feldspars and lower amounts of kaolinite and calcite. The obtained silica gels had pore diameters over 20 Å and specific surface areas up to 183 m 2 /g, close to those reported for commercial silica gel materials. The N 2 adsorption isotherms have shown that new materials synthesised from Tunisian silica sands are mesoporous materials with high chemi-physical adsorption capabilities." @default.
