3 Utilization of Zeolite Adsorbent for Defluoridation of Drinking Water

The presence of Fluoride ions in drinking water in concentration more than 1.5mg/lit is injurious to health. For this reason its removal is very essential from potable water. This paper describes the use of Zeolitic adsorbent (scolecite) from Ahmednagar (Pune) area in India, for separation of fluoride ions from the water. Fluoride ions are found to be retained on the zeolite bed while many other ions migrated either partially or completely. Worldwide drinking water is greatly contaminated with fluoride ions in certain areas. This idea can be developed on large scale for the removal of fluoride from drinking water.
