Abstract:

Fluoride accounts for about 0.3 g/kg of the Earth’s crust and exists in the form of fluorides in a number of minerals. Any water resource having fluoride concentration above permissible limit 1.5 mg/l (WHO Standards) requires treatment before usage. When the fluoride ion exceeds the permissible limit it causes dental fluorosis and then skeletal fluorosis. In this study, we have collected groundwater sample from 4 different locations (selected on the basis of fluoride existence) in TamilNadu and defluoridated them using our proposed technique which uses corncob (agriculture waste) and leca balls (Cheap Factory made) as adsorbents. Results shows that proposed technique can be practised for defluoridating the water sources for the removal of excess fluoride content. Notably, our proposed technique does not involve any use of chemicals.
