The present work deals with the removal of fluoride from synthetic water using mosambi (Citrus Limetta) peel powder in a batch reactor. The effects of time and initial concentration of fluoride on the % removal have been studied. Kinetics parameters and equilibrium constants have been computed from various kinetic and equilibrium models. Adsorption of fluoride on to Citrus Limetta obeyed the pseudo second order rate equation. The equilibrium data were found to fit well with Freundlich isotherm for adsorbent.
