Abstract This work was planned to synthesis the magnetic iron oxide nanoparticles fabricated layer double hydroxide/cellulose (Fe3O4@LDH/poly) nanocomposite adsorbent for fluoride adsorption from drinking water. The synthesized material was characterized by FTIR, XRD, SEM with elemental mapping and TEM analysis. The synthesized smart material was subjected to batch adsorption studies with the various parameters like contact time, adsorbent dosage pH, initial concentration and effect of foreign ions. The studies of isotherm, kinetic model and thermodynamics show the well-fitted isotherm order of the adsorption process, spontaneous and feasibility of the reaction. The adsorption process follows Freundlich adsorption isotherm with the correlation coefficient (r) of 0.998 and pseudo second order kinetic model. The maximum adsorption capacity of the adsorbent found to be 167.62 mg F−. g-1. This smart material was further examined for their fluoride removal capacity in nearby fluoride rich villages.
