| 摘 要： | 提供饮水降氟用的海泡石,系陕西省境内所产。矿体呈细脉状、网脉状,产于秦岭群大理岩裂隙中。矿石的矿物成分主要是海泡石和方解石;化学成分以 SiO_2、MgO、CaO 为主;总比表面大,具较强的吸附性。海泡石试样经明矾活化处理后,按照试验选择的降氟条件,对采自高氟地区的饮用水进行交换处理。实验性降氟表明,海泡石能使高氟饮用水降到符合国家规定的饮用水含氟标准。

| Abstract: | Sepiolite in Shaanxi mainly occurs in marble fissures of the Qinling Gr- oup.Its chemical components are mainly SiO_2,MgO and CaO.It is charac- terized by the large specific surface and the intensely absorptive power.Tre- ated by alum activation,sepiolite can be used to purify the fluorine-bearing water sampled from high fluorine area.The experiments show that sepiolite can purify fluorine-bearing water into the potable standards regulated by the state. |
