- 中文摘要: Thermodynamic and kinetics of adsorption of basic dyes (methylene blue and basic blue 3) on wood charcoal activated at 800 °C, prepared from Bombax Cieba (M78D) was investigated. Equilibrium data was obtained using batch method at temperatures of 10 °C to 50 °C. It was found that adsorption increase with increase in temperature. The Langmuir isotherm model describe the equilibrium of adsorption. Thermodynamic parameters such as DS°, DH° and DG° were calculated. From the values of DH° and DG°, it was concluded that the adsorption process is endothermic and spontaneous in nature. To determine kinetics parameter Lagergren equation was applied, and it was found that the reaction proceed through first order kinetic mechanism.
