摘    要:研究了改性前后膨润土对含氟废水的处理能力,以及F-浓度、时间、膨润土用量及温度对吸附的影响.结果 表明:用10 g/LMg-Al溶液改性后的膨润土的吸附能力明显增强,对F-浓度为20 mg/L的低氟废水的去除率由改性前的12.7%提高到74.72%,且随膨润土用量的增加,去除率明显提高.

关 键 词:膨润土  F-  去除率  吸附含量

Abstract:The removal of fluorine with different kinds of bentonite were presented in this paper.The performance of bentonite and modified bentonite to adsorb fluorine were compared.The results showed that adsorbing capability of modified bentonite was better than before.The removal ratio of fluorine increased from 12.7% to 74.72%.
Keywords:bentonite fLuorine ion removal adsorbing capacity
