摘要：

We studied the elimination of fluorides from underground water by adsorption on chitosan followed by electrodialysis with the help of the CMX-ACS membranes. After determining the optimal conditions of the defluorudation of a synthetic water by the chitosan extract from the chitin of the pink shrimps, we applied it to underground water of the city of Youssoufla. Another application has been made by electrodialysis of which the optimal conditions of treatment have been pre-established. A comparison of the two processes is also given. © 2004 Elsevier B.V.
