活性氧化镁处理高氟水的试验研究

文章以活性氧化镁作为吸附剂进行了降氟试验,通过pH-3C型酸度计考察了氧化镁投入量、pH值、温度和反应时间等因素对降氟效果的影响,并做了正交试验得到了最佳反应条件。实验结果表明,活性氧化镁降氟效果的最优化条件为：氧化镁的用量为0.30 g、反应时间为40 min、溶液的pH值为7.0、反应温度为40℃,产率为83.56%。此外与活性氧化铝作为吸附剂的降氟效果相比,其降氟效果要明显强于活性氧化铝。

The Ivestigation on the Effect of Lower Fluoride Using Active Magnesia

The effect of lower fluoride was investigated by using active magnesia as sorbent.The correlation influencing factors,such as active magnesia inputs,solution pH,temperature and reaction time,were discussed by pH-3C acidimeter.The optimal reactive conditions were obtained through Orthogonal experiment,which was following as 0.30g active magnesia,solution pH=7.0,reaction temperature 40℃,reation time 40 minutes and yield 83.56%.Furthermore,the active magnesia has the better effect of lower fluoride comparing with active alumina.
