dc.description.abstractBackground: The aim of this study was to evaluate the adsorption potential of natural and locally available soapstone and Calcium bentonite clay for fluoride removal from aqueous solution and to determine the optimum conditions for use. Adsorption potential was anchored on the availability of hydroxyl and aluminum ions inherent in both minerals which have been established to have ability for fluoride adsorption in aqueous solutions. Adsorption potential was investigated using batch equilibrium experiments. Materials and Methods; Mineralogical characterizations were done using X-ray fluorescencespectroscopy. Fluoride ion selective electrode was used in determination of fluoride content in aqueous solution.Optimization studiesoninitial pH of the solution, contact time, initial fluoride concentration, adsorbent dose, and heat pretreatment of the adsorbent were done in batch adsorption experimentsat room temperature. Results:It was observed that calcium bentonite exhibited better adsorption capacity of 0.21mg/g while soapstone had 0.08mg/g at a contact time of 45 min and 5 min respectively.The optimum pH for both adsorbents was established at 3.6. The experimental data for bentonite fitted well with Langmuir isotherm indicating a monolayer adsorption while for Soapstone fitted better into Freundlich adsorption, indicating multilayer adsorption with heterogeneous energetic distribution of active sites. Conclusion:Based on these findings, the two adsorbents can be fitted into household defluoridation apparatus for domestic remediation of fluoride contaminated water.en_US
