- Abstract
In this study, the adsorption behavior of fluoride has been investigated using the biomass derived activated hydrochar (AHC) prepared by a two-stage carbonization process. The adsorption process was spontaneous and exothermic in nature. The adsorption equilibrium data fitted to Langmuir isotherm. The maximum fluoride loading capacity (Qm) of AHC was found to be 88.7 mg/g. The adsorption process was spontaneous and exothermic in nature. Electrostatic interaction between the anion and the positive functional groups in the adsorbent was the main driving force for the adsorption of fluoride. Hence, activated hydrochar can be promising as an effective adsorbent to treat fluoride contaminated water.
