CHARACTERIZATION AND PREPARATION OF ARTOCARPUS HETEROPHYLLUS BARK POWDER AND USE AS AN ADSORBENT FOR REMOVAL OF FLUORIDE IONS FROM GROUND WATERAmit Punia, A.K. Berwal and M.S. Narwal
Artocarpus heterophyllus bark powder was applied for the expulsion of Fluoride Ions from groundwater. Influence of pH, contact time, the dosage of adsorbent, temperature and the effect of initial concentration on the adsorption process was examined. The highest fluoride ion removal was at the range of pH of 6. Various researchers are using Freundlich and Langmuir isotherms for expulsion of fluoride Ions. The study concludes that the sufficient time for adsorption equilibrium of fluoride ion was 3 hours. Artocarpus heterophyllus characterization is done by using FTIR, XRD, and SEM.
