Fluoride is a ubiquitous element present in earth's crust and is also being added to the environment anthropogenically. It is the most electronegative of all elements. Fluorine is found in the soil and the content of Fluorine in the lithosphere varies between 100 and 1500 g/ton. Fluoride has gained importance due to its dual influences on human beings. In lower concentrations, Fluoride is an essential nutrient which aids in the formation of bones, prevents tooth decay, etc. Whereas in higher concentrations it causes flurosis , bristling of bones , curvature of bones, dwarfishness, mental derangements, cancer, etc. and in extreme cases even death. Here fluoride and chloride are removed by adsorption method. The materials used for removal are Sugarcane baggase and Eichornia crassipes which will be cheaper. Hence chloride and fluoride will be removed at a cheaper cost.
