[Manufacture of hydroxyapatite as a defluoridator and the mechanism of defluoridation for drinking water].
Hydroxyapatite as a defluoridator for drinking water is characterized by a large capacity of defluoridation, and easy and simple operation in application. The quality of drinking water is not changed, the sorbent is easy to be regenerated, and the second pollution does not occur after the treatment of drinking water with the sorbent. Hydroxyapatite method has advantage over the methods such as actived alumina, bone char and electrodialysis commonly used in defluorination of drinking water. It is for this reason that the components, structural feature, synthesis and application of hydroxyapatite and its mechanism of defluoridation are summarized in this paper.
