title: [Study on the regeneration methods of the synthetic hydroxyapatite as a material for defluoridation of drinking water].
abstract: The regeneration efficiencies of the synthetic hydroxyapatite saturated by fluoride using either sodium hydroxide method or surface coating method are studied and compared. Both static and dynamic conditions for surface coating regeneration method are also tested. The results showed that the regeneration efficiency of the synthetic hydroxyapatite saturated by fluoride treated by surface coating method is 46%-64%, more than two times of that of it treated by the traditional sodium hydroxide regeneration method.
