摘要：

In the present work, we propose to investigate the fluoridation of brine water by electrodialysis using a new exchange membrane. This membrane called ClNH2 was prepared by crosslinking chloro-sulfonated polyethersulfone (SO2Cl-PES) using aminated polyethersulfone (NH2-PES) reagent. The efficiency of the electrodialysis process at different NaCl concentration ranging from 0.5 to 3.0 g/L was evaluated by the determination of demineralization rate, the ionic flux transport (J), the fluo-ride concentration on the dilute side and the specific power consumption. After defluoridation of the treated solutions, ions fluoride concentrations become lower than the amount fixed by the World Health Organization for drinking water. This study shows clearly that the electrodialysis process using the ClNH2 membrane is very promising for the defluoridation of water.
