Abstract


Water pollution is a major problem to health and development of humans. The thermodynamic and kinetic parameters of activated rice husk ash (ARHA) for the defluoridation of water were carried out using Langmuir and Freundlich adsorption Isotherms. Results showed that activated rice husk ash is very effective in the defluoridation of water with about 86.1 % fluoride removal at a reaction time of 60 minutes. The values of ΔGads were found to be below -20 kJ mol-1, which is consistent with physisorption mechanism of adsorption. Fluoride adsorption on ARHA was found to be endothermic from the positive values of enthalpy of adsorption ΔHads. Also, ΔSads was found to be positive, indicative of a spontaneous adsorption process of the fluoride
