Sobre IBD

Cette étude porte sur la valorisation de la biomasse Aptenia cordifolia pour l’élimination du bleu de méthylène en solution aqueuse par adsorption. Après caractérisation du matériau (DRX, IRTF, MEB-EDX, BET et potentiel zêta), les paramètres opératoires ont été optimisés. Les résultats montrent que l’adsorption est favorisée par l’augmentation de la masse d’adsorbant, du pH et de la température. Les données cinétiques suivent le modèle du pseudo-second ordre (PSO), tandis que les isothermes sont décrites par le modèle de Langmuir, avec une capacité maximale d’adsorption de 51,60 mg.g⁻¹. L’étude thermodynamique indique un processus spontané, favorable et endothermique. Les essais de régénération confirment également le bon potentiel de recyclage de l’adsorbant.
