Abstract

. The adsorption capacity was determined by gravimetric analysis using weight measurements of the sample both before and after adsorption. Langmuir, Freundlich, and Temkin adsorption isotherm models were employed to analyze adsorption data. Thermodynamic analysis revealed that adsorption is exothermic and spontaneous, while kinetic studies showed it follows first-order behavior.
