Abstract
Fluoride is an acute toxin, with a rating slightly higher than lead and is present in ground water naturally or artificially. Groundwater in India displays the presence of harmful quantities of fluoride. Fluorspar is main constituent of sand. Under the ground in presence of water when this mineral gets appropriate condition for dissolution, it gets dissolve in water and fluoride ion’s get separated from sand. The presence of fluoride causes many health issues to human beings. To reduce these health problems, there is a need to remove fluoride ions from water. This article is brief on different techniques for the removal of fluoride from water.
Highlights
Fluoride is present in sellite (MgF2), Cryolite (Na3AlF6), fluorspar (CaF2)
Under the ground in presence of water when this mineral gets appropriate condition for dissolution, it gets dissolve in water and fluoride ion’s get separated from sand
Fluoride occurs naturally in many minerals present inside the ground, like fluorspar, feldspar etc. in presence of water when it gets desirable conditions for solubility it gets dissolved in ground water and separates in form of F- ions and it is very difficult to remove these ions from water
