Optimization of adsorption performance by mesoporous materials developed from local clays and zeolite. Application in the treatment of real pharmaceutical effluents.

The treatment of effluents from the pharmaceutical industry currently remains a major challenge due to their impact on the environment and public health along with the cost of treatments. Considering these issues, our work focused on the development of materials with effective adsorption properties to treat industrial effluents based on locally available and inexpensive clays and zeolite. Local Algerian kaolin (Djebel Debbagh), palygorskite (Ghoufi) and zeolite (Tinbdar) were treated thermally and chemically prior to synthesis into mesoporous materials of hexagonal structure using pluronic P123 as surfactant.

Mesoporous silica synthesized from natural local kaolin as an effective adsorbent for removing of Acid Red 337 and its application in the treatment of real industrial textile effluent.

This paper presents a synthesis of mesoporous silica (MS) from natural clay as a silica source using Pluronic L35 (EO11PO16EO11) as a structure-directing agent. The prepared material was characterized by XRD, X-ray fluorescence, thermogravimetric analysis, SEM, TEM, and N2 adsorption-desorption analyses. Then, mesoporous material was used for the removal of Acid Red 337 (AR337) from aqueous solution, and the treatment of real textile effluent.
