Abstract

In this research work, a new biocomposite namely MOH@n-HAp/Alg biocomposite was developed by the musa ornata husk on nano- hydroxyapatite (n-HAp)/ alginate (Alg) biocomposite for defluoridation in batch mode. The synthesized biocomposite possess an enhanced defluoridation capacity (DC). The structural changes of the adsorbent, before and after fluoride sorption were studied using FTIR, XRD and SEM with EDAX techniques. There are various physico-chemical parameters such as contact time, pH, co-existing anions, initial fluoride concentration and temperature were optimized for maximum fluoride removal. The equilibrium data was well modeled by Freundlich, Temkin, D-R and Langmuir isotherms. The present systems follows Freundlich isotherm model. The thermodynamic parameters revealed the nature of adsorption are feasible, spontaneous and endothermic nature of fluoride sorption. The efficiency of the adsorbent material was examined with polluted water samples using the standard procedure.
