| 제목 | Equilibrium, Isotherm, Kinetic and Thermodynamic Studies for Adsorption of 2-Picoline from Taxus chinensis onto Sylopute |
| 초록 | Abstract Batch experiment studies were carried out on the adsorption of the major tar compound, 2-picoline, derived from the plant cell cultures of Taxus chinensis, using Sylopute while varying parameters such as initial concentration, contact time and adsorption temperature. The experimental data were fitted to the Langmuir, Freundlich, Temkin and Dubinin-Radushkevich isotherm models. Comparison of results revealed that the Langmuir isotherm model could account for the adsorption isotherm data with the highest accuracy among the four isotherm models considered. From the analysis of adsorption isotherms, it was found that adsorption capacity decreased with increasing temperature and the adsorption of pure 2-picoline by Sylopute was favorable. The kinetic data were then fitted using pseudo-second-order and intraparticle diffusion models. Thermodynamic parameters (△H°, △S°, △G°) revealed the exothermic, irreversible and nonspontaneous nature of adsorption. |
