Optimized Removal of Hydroquinone and Resorcinol by Activated Carbon Based on Shea Residue (Vitellaria paradoxa): Thermodynamics, Adsorption Mechanism, Nonlinear Kinetics, and Isotherms
Published 2022-01-01“…Temkin’s two-parameter model shows that adsorption occurs on heterogeneous surfaces with a nonuniform adsorption energy distribution at the surface and Sips’s three-parameter model confirms the heterogeneity of the surface with a localized adsorption of HQ or R by CAK-S. The thermodynamics study has shown that the adsorption is endothermic (ΔH0 >0) and spontaneous (ΔG0<0).…”

Ultrasonic-assisted adsorption of methylene blue using shrimp shells as a low-cost adsorbent: Evaluation on the adsorption isotherm, kinetics, and thermodynamics
Published 2025-04-01“…The adsorption kinetics study revealed that the experimental data for all three adsorbents conformed well to the Pseudo-Second Order model, with R2 values ranging from 0.99998 to 1.0000. Finally, the thermodynamic assessment demonstrated that ultrasonic-assisted MB adsorption with the three adsorbents was spontaneous, with ΔG° values of -1,542, -10,669, and -10,680 kJ/mol, ΔS° values of 62.845, 150.900, and 162.260 kJ/mol.K, and ΔH° values of 17,347, 35,088, and 38,339 kJ/mol for A1, A2, and A3, respectively.…”
