الملخص

This research work is part of the valorization of microporous materials for the treatment ofwater contaminated by industrial dyes, particularly malachite green in its oxalate form. Thestudy focused on magadiite, a lamellar-structured phyllosilicate, modified through theintercalation of an organic molecule N-(1-naphthyl) éthane-1,2-diamine dihydrochloride inorder to enhance its adsorption capacity.In order to achieve our objective of obtaining an optimal adsorption yield, a study of adsorptionisotherms and kinetics was carried out. The analysis of the isotherms revealed that theadsorption process can be modeled using the Langmuir, Freundlich, and Dubinin–Radushkevichisotherms. The optimal parameters studied include: the mass of the adsorbent, agitation time,solution concentration, and pH. Adsorption kinetics were analyzed using the pseudo-first-orderand pseudo-second-order models.The study of adsorption isotherms showed a clear improvement in the maximum adsorptioncapacity following intercalation: the Langmuir model yielded a value of 323 mg/g compared to4.40 mg/g before modification, and the Freundlich model revealed a significant increase in theKF coefficient.The results confirm the effectiveness of organic intercalation in optimizing the adsorptiveproperties of magadiite, both in terms of efficiency and selectivity. The modified material thusrepresents a promising and sustainable alternative for the removal of dyes from industrialeffluents.
