吸附除氟材料研究新进展

Recent research on defluoridation material by adsorption:a review

氟是人体内重要的微量元素之一,但在水中如果其浓度过高,将会对人体和环境造成很大危害。如何去除水中的氟备受科研工作者的关注。在众多方法中,吸附法可以简单、有效地去除饮用水中的氟离子,因此得到广泛应用。新型除氟材料成为当前研究的热点。综述了近年来国内外关于除氟材料的最新研究进展,包括天然矿物、金属氧化物、生物材料、类水滑石、树脂类和废弃物等材料,并探讨了各种除氟材料的除氟机理。通过对国内外研究成果的总结与分析,展望了除氟材料进一步研究的发展方向。

Fluoride is one of the essential element for human,but excess amount of fluoride in drinking water impose a serious threat to human health and environment.Among several treatment technologies applied for fluoride removal,adsorption process has been a simple and effective method,can be widely used for fluoride removal.The novel defluoridation material has become hotspots.Recent advances on the defluoridation material in the domestic and foreign were reviewed.The present status of all kinds of defluoridation materials,such as the nature minerals,metallic oxide,like-hydrotalcites,the biology materials,the resin and industrial and agricultural wastes were reviewed in detail.The adsorption mechanism for the mentioned materials was discussed,and the development aspect was also prospected.
