ABSTRACT

Fluoride is the major inorganic pollutant of natural origin found in groundwater. Fluoride in minute quantity is an essential component for normal mineralization of bones and formation of dental enamel. Since then considerable work has been done in different parts of India to explore the fluoride laden water sources and their impacts on human as well on animals. The safe limit of fluoride in drinking water is 1.0 mg/L. Water with high fluoride content is generally soft has high pH and contains large amount of silica. In groundwater, the natural concentration of fluoride depends on the geological, chemical and physical characteristics of the aquifer, the porosity and acidity of the soil and rocks, temperature, the action of other chemicals and the depth of wells. The solution to the problem is removing the excess of fluoride form water. There are a number of processes that are used for the De-fluoridation purpose. Some of the methods used are: Synthetic ion exchange, Precipitation processes, and Activated alumina filters, Reverse osmosis, Absorption techniques. Mostly applied technique is absorption either with the chemical, physical or biological adsorbents. These bio-adsorbents have the property of adsorbing various metal ions. Here various naturally occurring adsorbents are used which have shown a desirable amount of degradation in Fluoride content of water sample. In this report the data obtained reveals that various adsorbents used are highly efficient in fluoride removal.
