摘要
The rarefaction of drinking water resources led certain populations of different countries to use water which has a high fluoride content, above the W.H.O. limit, resulting in dental and osseous fluorosis. The present work has proved that the Donnan dialysis could be a suitable method for removing the fluorides. The systematic study of the different parameters involved showed that stirring and the membrane characteristics are the main variables affecting the transmembrane flow. The rough computation of a defluoridation unit shows that the process is viable. (C) 1997 Elsevier Science Ltd.
