| Abstract: | This paper involves preparation of ferric-modified permutite in lab scale,as well as static and dynamic adsorption column tests in order to study removal of fluoride from water.The dynamic adsorption study reveals that the equilibrium adsorption data fit well to Langmuir adsorption isotherm with equilibrium constant of 0.030 2 L/mg,and the max adsorption capacity is 9.83 mg/g.Regeneration of the modified permutite that has been fluoride-saturated is made possible by elution with sodium hydroxide followed by... |
