Abstract

according to the Langmuir isotherm model. The Elovich model, suggested adsorption on energetically heterogeneous surfaces, while equilibrium data follow the Dubinin-Radushkevich isotherm, indicating a predominantly physical adsorption, best described kinetic data. Thermodynamic analysis further revealed that the process is spontaneous and exothermic. Finally, process optimization using a Box-Behnken design (BBD) under response surface methodology showed high model predictability, establishing this composite as a cost-effective and eco-friendly solution for the remediation of dye-contaminated effluents.
