Study on the Defluorinated Materials of High Fluoride

Abstract:

In our country, high fluoride containing groundwater is general. Now,there have been some study on fluoride containing groundwater, but MgSO4 is the first use. In this paper,therefore,study a new method for removing fluorine from groundwater with MgSO4 , CaO powder regulate pH, studies the influencing factors of fluorine removal rate, such as pH,temperature and so on, obtain the proper treatment condition:8% MgSO4 solution 10ml, CaO powder regulate pH11,stir 5min at 40°C. Using this method, the concentration of fluorine ion in the groundwater is lower than the national provided drinking water criterion of <1.0mg/L, fluorine removal rate reach 93%.
