Abstract: Chronic drinking of ground water containing high concentration of fluoride causes health damage to a large quantity of population in north China, which is not conducive to human health. The work of defluorination for high-fluorine groundwater economically and efficiently is the focus of research. In this paper, the principles, advantages and disadvantages of the existing process of removing fluoride from groundwater are summarized, and some research suggestions are given.

Keywords: groundwater; defluorination; progress

氟元素是地殼中含量較多的元素之一,主要以含氟礦物質(zhì)形式存在,目前已知的含氟礦物質(zhì)約有80多種,主要有冰晶石(Na3AlF6)、螢石(CaF2)、氟鎂石(MgF2)、磷鋁石(AlPO4(F,OH))、磷鐵錳礦((Mn,F(xiàn)e2+)2(PO4)(F,OH))等。(剩余10786字)
