摘要
本文论述了以镁矿为原料制得的镁系吸附剂,用于含氟工业废水和高氟饮用水的除氟。该镁系吸附剂的类型有:H-MgO,x-MgO,F_1-MgO,F_2-MgO。在25.5~44.2PPm 的 F^-水中加入0.2%的吸附剂,其除氟率为91.0~98.7%。回收使用后的吸附剂可在600~700℃灼烧再生、重复使用。
Efficiency in the removal reaction of fluoride from wast water and drinking water by the Mg-sys- tem adsorbent being developed us has been ostudied. The sorbent is made by ore of magnesium,it named H-MgO,X-MgO,F<sub>1</sub>-,F<sub>2</sub>-MgO.about 91.0 ~98.7% of fluorine be removed form the solution contained 25.5~44.2PPm as F-by the Mg-system adsorbent 0.2%. The used adsorbent was able to recycle for the removal process,after reclamation with burning it at about 600~700C.
