Abstract: Today, microporous solids, such as zeolites, occupy a prominent place in the industrial field and are an interest potential in various applications; Such as include gas drying, purification, refining, catalytic and ion exchange processes, the environment and even in the nuclear industry. It is because of their very remarkable properties "Adsorbents" that these materials have invaded our life.

In fact, the microporous systems of these materials are at the origin of numerous filtration and purification processes in liquid phase as well as in the gas phase, due to their excellent adsorption capacity; Capacity linked to their large surface area and the development of their porosity. In addition, the recycling and regeneration of adsorbed products are relatively easy, the long service life of the adsorbent solids is also a considerable advantage.

The aim of this work is the elaboration of a NaX zeolite modified by the incorporation of organic complex in the porous network.

Incorporation of the surfactant into the zeolite framework slightly increased the specific surface area of the modified NaX material. The surface area increases from 32 to 64 m2/g, but the surface area increases to 405 m2/g after calcination of the modified NaX material.
