Exploring the Efficiency of Algerian Kaolinite Clay in the Adsorption of Cr(III) from Aqueous Solutions: Experimental and Computational Insights

Molecules, Journal Year: 2024, Volume and Issue: 29(9), P. 2135 - 2135

Published: May 4, 2024

The current study comprehensively investigates the adsorption behavior of chromium (Cr(III)) in wastewater using Algerian kaolinite clay. structural and textural properties clay are extensively characterized through a range analytical methods, including XRD, FTIR, SEM-EDS, XPS, laser granulometry, N2 isotherm, TGA–DTA. point zero charge zeta potential also assessed. Chromium reached equilibrium within five minutes, achieving maximum removal rate 99% at pH 5. Adsorption is modeled Langmuir, Freundlich, Temkin, Elovich, Dubinin–Radushkevitch equations, with Langmuir isotherm accurately describing process yielding capacity 8.422 mg/g for Cr(III). Thermodynamic parameters suggest spontaneous endothermic nature Cr(III) sorption, an activation energy 26.665 kJ/mol, indicating importance diffusion sorption process. Furthermore, advanced DFT computations, COSMO-RS, molecular orbitals, IGM, RDG, QTAIM analyses, conducted to elucidate adsorption, revealing strong binding interactions between ions surface. integration theoretical experimental data not only enhances understanding but demonstrates effectiveness this adsorbent treatment. highlights synergistic application empirical research computational modeling elucidating complex processes.
