Abstract

This research conducted a thermodynamic and kinetic investigation of the adsorption of environmentally detrimental organic amino compounds, such as aniline and diphenylamine, from aqueous solutions onto bay leaves as an adsorbent. The study examined the influence of various factors on adsorption, including initial adsorbate concentration, pH, and temperature. Additionally, adsorption isotherms were determined. The findings revealed that the interaction between the amino compounds and the bay leaf surface was rapid, reaching equilibrium within 50-70 minutes. Furthermore, adsorption increased with an increase in adsorbent dosage. Temperature and pH impacted adsorption significantly; higher temperatures and acidic conditions (pH 7) favored increased adsorption. The adsorption isotherms indicated a non-spontaneous process. Correlation coefficient analysis revealed a strong resemblance between the experimental data and the Freundlich isotherm while deviating from the Langmuir isotherm. Regarding adsorption kinetics, the study concluded that the process followed a pseudo-second-order model.
