Abstract
Removal of fluoride using coconut shell carbon (CSC) was investigated in batch system. The fluoride removal performance of the coconut shell carbon (CSC) was evaluated as a function of the feed fluoride concentration, adsorbent dose and pH. The adsorbent was characterized as having high selectivity for fluoride and larger adsorption capacity. Adsorption was faster at the beginning followed by slower removal. pH was found to be a decisive parameter for fluoride removal. The experimental data followed the Freundlich isotherm model. Application of CSC for the effective removal of fluoride from water has been demonstrated.
