| Research Abstract |
The improvement of the fluoride adsorption capacity and regeneration condition of Si-Al-Mg mixed hydrous oxide was considered to establish the technique that can remove fluorine drained from a hot-spring hotel. A synthetic method of Si-Al-Mg mixed hydrous oxide was established to improve fluoride adsorption capacity, and nitric acid pollution was able to evade at the same time. Furthermore, a kind and the concentration of most suitable regeneration solution to reuse adsorbents were clarified. The fluorine removal technology that we can introduce into a hot-spring hotel will be established by Si-Al-Mg mixed hydrous oxide being granulated appropriately.
