WebThe adsorption rate was extremely fast and the equilibrium was reached within 8 min. The adsorption isotherms of the adsorbent were preferably fitted to the Langmuir model, with the maximum adsorption capacity of 88.4 mg/g at 25 degrees C. Thermodynamic parameters indicated the spontaneous and exothermic nature of adsorption.
