The study reveals the suitability of inexpensive adsorbents to effectively remediate fluoride (F) contaminated water. Bark of Azadirachta indica (Neem) and Acacia nilotica (Keekar) plants was used to defluoridate water samples. The efficiency of the sorption of F is affected by pH, contact time and adsorbent dose. Maximum percent removal of F was obtained on pH 6 and 60 minutes of contact time with 5 ppm standard solution of F. Significant adsorption of F occurred on 1.2 gm/100ml dose of Neem adsorbent and 1.0 gm/100ml dose of Keekar adsorbent. The adsorption equilibrium is well correlated by Freundlich model for both the adsorbents. These findings would be helpful in development of cheap and safe fluoride removal technology.
