| Abstract: | In this paper the results of experimental studyon removal of fluoride from water by calcium phos-phate were presented. At pH 6. 2～7. 5, when Ca~(2-)and PO_4~3 in proper proportion to F were addedinto water with excess fluoride, the fluoride con-tent in water could be reduced below 0. 8 mg/L.This method of defluoridation is reliable, cheap,simple and convenient. So it is easy to be widelyused in countryside, small and middle towns.Moreover, it is impossible for this measure to re-sult in any new chemical pollution. |
