Abstract
This study aims to assess the fluoride sorption by the use of Bentonitecategorized into four groups that isBentonite (B), activated Bentonite(8000C) (BAA), Bentonite impregnated with iron (BI) and Bentoniteimpreginated withaluminium(BA). Characterization was done by XRF before and after impregination, showed that highest percentage composition of SiO2, CaO, P2O5, Fe2O3 and Al2O3. XRD revealed higher composition of illite, calcite, quartz and albite. Batch experiments were conducted by using homogeneous mixture of water having 16 mg/L of fluoride measured by fluoride ion selective electrode. All adsorbents were found to be effective on removing fluoride ions from fluoride bearing water with removal efficiency of 83.73% for BAA, 92.70% for BI and 94.98% for BA except Bentonite (B) alone which showed negative result. The optimum pH were found to be 8, 3, 7 and the optimum doses of 9, 8 and 7 g, optimum contact time of 70, 60 and 50 minutes respectively with the batch volume of 50 mL.The adsorption process obeyed Langmuir model for BAA and BI, for BA agreed with Langmuir and Freundlich models.For the kinetics perspective, the fluoride adsorptive reaction followed the pseudo-second order model. Therefore, the activated and impregnated Bentoniteis the alternative and cheap adsorbents for water defluoridation.
