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

[Display omitted] • CV adsorption onto FeTiPbONCs was interpreted using statistical physics model. • The Nm values obtained 355.85, 50.91 and 26.815 mg/g at temp. 298, 308 m, and 318 K. • The adsorption energy ε 1 (16.95 to 30.39 kJ/mol) and ε 2 (7.98 to 13.02 kJ/mol). • The double layer model best explain the adsorption behavior and mechanism. 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 ε 1 (from 16.95 to 30.39 kJ/mol) and ε 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. [ABSTRACT FROM AUTHOR]
