Description
Summary:Fluorine in the form fluoride is one the few elements that could cause healthiness trouble with together its insufficiency and surplus intake. For instance, the surplus fluoride in potable water leads to fluorosis. In this present study, magnetic iron oxide/graphene oxide/alginate/zirconium-organic frameworks (MGOAZ) based hybrid beads were fabricated and it was applied for defluoridation experiments. Several instrumental characterization techniques like EDAX, XPS, FTIR, SEM and XRD were studied to find the surface properties (physical and chemical) of fabricated MGOAZ beads material. Batch fluoride adsorption tests were performed to notice the fluoride adsorption action. The maximum defluoridation capacity (DC) of developed MGOAZ beads was attained at pH 7. Adsorption kinetics and isotherm equilibrium data for fluoride adsorption of the developed MGOAZ beads were vitally followed by pseudo-second-order/intraparticle and Langmuir isotherm model. Thermodynamic exploration exhibited that the adsorption route by MGOAZ beads was endothermic with spontaneous nature. Moreover, electrostatic attraction and complexation mechanism possess substantial role during fluoride adsorption onto the developed MGOAZ beads. Moreover, the regeneration performance and field suitability of MGOAZ beads was discussed in detail. [Display omitted] •MGOAZ beads were utilized for defluoridation studies.•MGOAZ beads remove fluoride both in standard and field water.•MGOAZ beads are regenerable and provide water with safe fluoride levels.
