Investigations are made on the removal of fluoride from water by prepared activated carbons. Three activated carbon adsorbents, BKC, BOC and RSC are prepared from selected biomaterials of bergera koenigh, batavia orange and raphanus sativus respectively. The adsorption capacity towards adsorption of fluoride from aqueous solution was studied and was determined by using fixed amount of adsorbent(0.1g/100mL) and a known concentration of adsorbate (5mg/L) solution at 30 minutes agitating time. The data have been analyzed in the light of adsorption isotherms, adsorption kinetic equations and intraparticle diffusion model. Regeneration of adsorbents was studied.
