Statistical modeling and interpretation of Sono-assisted adsorption mechanism of Crystal Violet dye on FeTiPbO Nanocomposite

In this study, Crystal Violet (CV) adsorption isotherm on FeTiPbONC was simulated and interpreted using the conventional methods as well as statistical physics two energies double layer model. This model was formalized based on the statistical physics. The following parameters are added in this pattern: steric and energy-sensitive parameters relevant to the adsorption mechanism. The findings of the mathematical model at temperatures 298, 308 , and 318 K givethe values of receptor site density (Nm) as 355.85, 50.91 and 26.815 mg/g, which reveals that maximum adsorption was achieved at lower temperature. The adsorption energies epsilon(1) (from 16.95 to 30.39 kJ/mol) and epsilon(2) (from 7.98 to 13.02 kJ/mol) increases as temperature rises, showing that the CV-FeTiPbONC contact is stronger than the CV-CV interaction. The results showed that FeTiPbONC might be employed as a nanoadsorbent for the removal of organic contaminants from an aqueous matrix. (C) 2021 Elsevier B.V. All rights reserved.
