Assessment of Adsorption Process and Mechanism for Methylene Blue Removal on Cranberry: Isotherm, Kinetic and Thermodynamic Studies

Öz

In the present study, cranberry based adsorbent (CBA) was used for the removal of Methylene Blue (MB) from aqueous solutions. The influences of operational parameters, including initial MB concentration (15–75 mg L⁻¹), temperature (298 K–318 K) and contact time (10–180 min), were systematically examined. The removal efficiencies at the 35 mg L⁻¹ initial MB concentration were determined to be 79.3%, 82.9% and 85.8% at the 298 K, 308 K and 318 K, respectively. The maximum adsorption capacity (qₘ) was achieved at 91.743 mg g⁻¹ at 318 K. Experimental data were evaluated using adsorption isotherm models, kinetic studies and thermodynamic analyses. Temkin model was provided the best fit to the experimental data among the applied four isotherm models (Langmuir, Freundlich, Dubinin–Radushkevich and Temkin). Adsorption kinetics were evaluated with three models and adsorption process was followed the pseudo second order (PSO) kinetic model most accurately, which has the highest R² values. Thermodynamic analysis for adsorption of 65 mg L⁻¹ initial MB concentration at 318 K was revealed negative values for Gibbs free energy (-2942.16 J mol⁻¹), along with positive enthalpy values (16618.02 J mol⁻¹) and entropy (61.51 J mol⁻¹K⁻¹). These results were showed that adsorption process was spontaneous and endothermic in nature and the activation energy was calculated to be 14.44 kJ mol⁻¹. These results suggested that prepared cranberry adsorbents was represented a promising low-cost alternative to conventional adsorbents for effective removal of dye pollutants from wastewater.
