Removal of Fluoride from Ground Water by Using Bio-Adsorbent like lantana camera ( Jamri )

Drinking water contamination by fluoride is recognized as a major public health problem in many parts of the world. In fact, although fluoride is an essential trace element for animals and humans, excessive fluoride intake may cause adverse health effects. Among several treatment technologies applied for fluoride removal, adsorption process has been explored widely and offers satisfactory results, so objective of this study was to investigate or check efficiency of low cost adsorbent The feasibility of low-cost biomass based adsorbent like lantana camera used for defluoridation of ground water at different pH and contact time the effect of this adsorbent on fluoride removal was compared with other available adsorbents. It was found to be much better adsorbent with high removal efficiency at higher concentration (5 ppm) of fluoride in ground water. The effect of time for adsorbent and initial concentration of fluoride on the % removal was also studied. Adsorption was found to be pH dependent with maximum removal efficiency at pH 7.0 (in neutral medium).
