ÉTUDE SPECTROSCOPIQUE DE LA DÉGRADATION ET/OU PIÉGEAGE DE POLLUANTS PAR DES SOLIDES POREUX ECHANGÉS

Abstract

Zeolites are alumino-silicates materials whose pores have a characteristic size comparable to the size of various organic or inorganic molecules. They have some interesting adsorption and catalytic properties, porous solids have been the subject of many studies regarding their potential uses in various fields. Many researchers have focused then on getting these new compounds, especially the material named MCM- 41. Its synthesis is based on the use of a cationic surfactant, the materials obtained for this synthesis have good surface area and pore openings large enough so the synthesized MCM-41 are quite capable of being used as a trap for some metals such as lead and cadmium levels with evidence of trapping.
