Abstract

Fluoride is an essential constituents for both humans and animals depending on the total amount ingested or its concentration in drinking water. The presence of fluoride in drinking water, within permissible limits of 0.5-1.0 mg/l, is beneficial for the production and maintenance of healthy bones and teeth, while excessive intake of fluoride causes dental and skeletal fluorosis. An attempt is made to study the various materials available with special reference to different methods of defluoridation and different natural adsorbents used for defluoridation by adsorption technique. Different activated adsorbent samples like activated alumina, activated bauxite, Activated rice husk were taken and equilibrium studies were conducted to find a suitable adsorbent. The results obtained from these studies are presented in this report
