Preparation and Characterization of a Porous Material from Algerian Desert Sand

Ghania Mecheri , Said Hafsi , Noureddine Gherraf

The objective of the present work was to prepare and characterize a porous material using quite particular and localized dunar sand (erg) of the desert near the El-Oued (south-east of Algeria). The porous material was prepared according to the mechanism of co-operative self-assembly. The method was consisted of a polymerizing silicic precursor (sodium silicate obtained by alkali fusion of sand with the sodium carbonate) around micelles of surfactant in an acid aqueous solution according to the sol-gel process.  The elimination of the surfactant by calcining at high temperature led to the final material which was characterized by XRF, XRD, MEB-EDX, FTIR, and BET techniques.
