Construction of magnetic particles sprayed hydroxyapatite based bio-ceramic beads for selective fluoride removal

The current study concentrates on the fabrication of hydroxyapatite in an exploitable bead form with enhance defluoridation capacity (DC) and quick separation. Hence, magnetic iron oxide/alginate-gelatin/hydroxyapatite/ beta-cyclodextrin based beads (MAGHC bio-ceramic beads) were prepared and constructively utilized for fluoride retention from water. The responsible parameter for fluoride removal was performed by batch mode. The physicchemical properties of the developed MAGHC bio-ceramic beads were characterized with different sophisticated instrumental methods namely EDAX, SEM and FTIR studies. The different adsorption kinetic and isotherms studies were carried out to fit experimental data of fluoride adsorption onto MAGHC bio-ceramic beads. The fluoride adsorption method was thermodynamically feasible and endothermic nature. Defluoridation by MAGHC bio-ceramic beads was majorly governed by electrostatic interaction and complexation. The reusable and actual real water sample test also investigated using developed MAGHC bio-ceramic beads. The results revealed that MAGHC bio-ceramic beads could reusable and efficiently remove fluoride from drinking water at field condition.
