Résumé:
The issue concerns the releases of the pharmaceutical industry into the environment and is a
topical concern because they cause enormous harm to the environment and public health. As a
result, the use of local clays for the purpose of recovery in the treatment of effluents has an
important environmental interest.
This work is focused on the use of local clays and zeolite: DD3, attapulgite and natural zeolite
for the treatment of pharmaceutical effluents and recycling in a sustainable development
approach, and therefore by its contribution to the preservation of resources in water, as well as
the protection of the environment and human health.
The thermally and chemically treated clays (DD3 and attapulgite) and natural zeolite of Tinbdar
were synthesized into mesoporous materials of hexagonal structure using pluronic P123 and
CTAB as surfactants. The adsorption capacity of the materials was tested in the adsorption of
IBUPROFENE® with an optimization of the operating conditions by an experimental plan.
On the other hand, the study of the effectiveness of the process of adsorption of clays and
mesoporous zeolite was tested in the treatment of pharmaceutical effluents from NEUROVIT®
and DIAPHAG®. The analysis of the physicochemical parameters of the effluents showed that
the mesoporous kaolin DD3 is a promising adsorbent.
