  • Abstract

    The occurrence of high fluoride in groundwater has drawn considerable attention in the world. The contamination of fluoride in groundwater has influenced by fluoride rich rocks, pH, cation and anion exchange capacity of aquifer materials, bicarbonates, evaporation and temperature etc. The aloe (Aloe barbadensis Miller) and calcium chloride has been used to precipitate out fluoride ions from drinking water. The effect of different parameters on precipitation and adsorption studies like pH, agitation time, adsorbent dose and fluoride concentration have been analysed. The equilibrium adsorption data was studied for Langmuir and Freundlich isotherms
