    Abstract
    Capacitive deionization (CDI) is among the promising technologies employed for water purification. CDI has been studied for the removal of various ionic species from water including fluoride ion (F ) with promising results. However, there is no comprehensive literature that sum marizes the use of CDI for water defluoridation applications. Therefore, this review paper critically analyzes different electrode materials that have been studied for water defluoridation, their electrosorption capacities and F removal efficiencies. It further discussed the parameters that influence CDI efficiency during defluoridation and point out the issues of F selectivity when co-existing with other ions in the solution. We can conclude that different electrode materials have shown different abilities in electrosorption of F . The carbon-based materials pos sess high surface area and good electrical conductivity which is paramount for ion adsorption but gives lack selectivity for F removal. Metal oxides and hydroxides have been reported with improved electrosorption capacity and high selectivity to F due to the ion exchange between the F and the hydroxyls surface of the metal oxides/hydroxides. Apart from the good performance of these materials for defluor idation, the discovery of actual practical use of the electrode materials for defluoridation for commercial scale
