Abstract

Nitric acid-activated carbon prepared from the barks of Leucaenea leucocephala plant (NACBLL) is investigated as an adsorbent for the extraction of fluoride from contaminated water by varying different physicochemical parameters. The conditions for the maximum possible extraction of fluoride have been optimized. The adsorption capacity of the adsorbent is observed to be 1.16 mg/g. NACBLL is characterized for its different textual properties and its surface morphology was investigated by FT-IR, SEM and EDX methods. The results reveal fluoride adsorption. Adsorption isotherms and kinetics of adsorption are analysed using various models. Thermodynamic parameters are assessed. Desorption and regeneration studies of the spent adsorbent indicate that the % of extraction did not come down below 70.0% even after five regenerations for the adsorbent. The validity of the method developed is assessed with real polluted water samples.
