| 摘 要： | 笔者于1985年春,发现了我国迄今报道的品位最高的勃姆石矿。将勃姆石在650℃下焙烧0.5—1h,则可相变生成γ-Al2O3,其比表面积最大,利用这样的γ-Al2O3,可以有效地除去水中过量的氟。该工艺的水处理费用较低,有可能为高氟水地区的饮水降氟提供一条新途径。

| Abstract: | In the spring of 1985,the authors discovered a boehmite deposit.The mineral grade is the highest than ever known in China.When the boehmite was calcined at 650 ℃ for 0.5-1hr,it was transformed into γ-Al2O3,which has considerable specific surfacearea.Excess fluorine anions of groundwater ca,be reduced effectively by using this γ-Al2O3.The cost of this technology for water treatment is low.It can provide a new way for reducing fluorine in drinking water in the areas where the groundwater has high fluorine content. |
