To approximate conditions defluoridation groundwater, during this work, we are interested in the study of the influence of the presence of ions -counter on the ability of removing fluoride ions by chitosan. Also we searched the optimal conditions for the desorption using a basic solution. In light of this study, we observed that a NO₃^- and HCO₃^- share are the real competitors to the removal of fluoride on chitosan. And secondly, Desorption of fluoride from saturated support is possible and efficient with the addition of NaOH in our optimal desorption conditions.
