Description :
Chronic fluoride intoxication (fluorosis) is a worldwide health problem and India is endemic to fluorosis in 17 states. Fluorosis is originated mainly due to the consumption of drinking water containing high fluoride concentration. Among the available different deflouridation technologies, adsorption is one of the best due to its easy handling, low cost and high efficiency. Nowadays Nanosorbents are widely used as separation media in water purification to remove inorganic and organic pollutants from contaminated water. Two vital properties make nanoparticles highly lucrative as sorbents. On a mass basis, they have much larger surface areas compared to macro particles and they can also be enhanced with various reactor groups to increase their chemical affinity towards target compounds. In this work, synthesis and applications of various nano Dimensional materials for defluoridation of water are reviewed.
