摘要
近些年来,氧化铝由于其高比表面积、高活性、稳定性好的优点逐渐成为主要的除氟吸附材料,而改性后的氧化铝因具有更多活性位点成为除氟研究热点。介绍了几种除氟方法以及氧化铝除氟的机理,总结了金属改性(碱土金属、过渡金属、稀土金属)和表面活化在吸附除氟氧化铝改性中的研究进展,并对未来吸附除氟氧化铝改性发展方向提出展望。
In recent years,alumina has gradually become the main adsorption material for fluorine removal because of its high specific surface area,high activity and good stability,while modified alumina has become the focus of fluorine removal research because of its more active sites.In this paper,several methods of fluoride removal and the mechanism of fluoride removal by alumina were introduced,the research progress of metal modification(alkaline earth metal,transition metal,rare earth metal)and surface activation in the modification of adsorption fluoride removal from alumina was summarized,and the development direction of adsorption fluoride removal by alumina was prospected.
