In this present investigation, amine functionalized graphene oxide (AGO) doped on alginate (Alg) polymeric matrix gives [email protected] hybrid spheres was developed to explore its potential towards fluoride retention. The vital characterization techniques namely FTIR, TGA, SEM and XPS analysis of [email protected] hybrid spheres were acquired to identify its physicochemical properties. The liable parameters for fluoride adsorption onto [email protected] hybrid spheres were optimized in a batch mode to attain enhance defluoridation capacity (DC). The prepared [email protected] hybrid spheres follow the electrostatic interaction mechanism on defluoridation. The adsorption isotherms (Fruendlich, Langmuir, Temkin and Dubinin-Radushkevich (D-R) models), kinetics (reaction and diffusion based models) and thermodynamic parameters (ΔS°, ΔG° and ΔH°) were surveyed at 303, 313 and 323 K. To lessen the cost-effectiveness of [email protected] hybrid spheres the recyclability test was conducted. The aptness of [email protected] hybrid spheres was also scrutinized for the fluoride contaminated field sample collected from fluoride endemic village.
