Fluoride removal studies from contaminated ground water by using bauxite

►Fast kinetics and considerable adsorption capacity of 5.16 mg/g. ►pH dependent F- adsorption, by coulombic attraction and ion exchange interactions. ►Presence of other anions shows adverse effect on F- removal capacity. ►The optimum pH range of 5-7 makes it suitable for water treatment. ►Bauxite is a simple, cost effective and abundantly available mineral.
