Reduced graphene oxide /calcium alginate beads (rGO/calcium alginate beads) were composed of reduced graphene oxide and calcium alginate which was prepared by sol-gel method and characterized by SEM, TEM, XRD and IR. To study the effect of various factors like adsorbent dose, initial concentration, pH and temperature on fluoride and chromium removal from water using rGO/calcium alginate beads a series of batch sorption experiments were conducted. The obtained results were analyzed by Langmuir and Freundlich isotherms and it was found that fluoride and chromium removal closely follows Langmuir adsorption isotherm. The results were also analyzed through various kinetic models like Lagergreen pseudo-first-order kinetics, the pseudo-second-order kinetics, and the intraparticle diffusion model. Removal of fluoride and chromium from water is best described by the pseudo-second-order Lagergreen equation. It was also found that intra-particle transport is not the rate-limiting step.
