Abstract

With the rapid development of society, fluoride pollution in the water environment caused by human activities and natural development has constituted one of the main causes of threat to human health and safety. Among the various fluoride removal technologies available, adsorption technology has been deeply explored by various scientists and has made great progress in the current emergency situation of fluoride-contaminated water sources, especially the adsorbents containing metal or metal ion materials, which have better results. This review first describes the various mechanisms of fluoride removal by adsorption, the different methods of preparation of the materials (electrospinning, hydrothermal, solvothermal, and so on), and the current applications of the materials in fluoride removal. Then, in terms of application, the influence of different factors on the fluoride removal capacity is presented. Finally, solutions to the current problems are proposed. However, to apply them to industry for large-scale use requires the continued exploration of various researchers to make the theoretical effects into practical ones, thus improving the environment on which we depend.

用于去除废水中氟化物的先进含金属复合材料：机理、制备、性能和应用

随着社会的快速发展，人类活动和自然开发对水环境造成的氟化物污染已成为威胁人类健康和安全的主要原因之一。在现有的各种除氟技术中，吸附技术得到了各科学家的深入探索，在目前氟化物污染水源的紧急情况下取得了很大进展，特别是含金属或金属离子材料的吸附剂，效果较好。本文首先介绍了吸附除氟的各种机理、材料的不同制备方法（静电纺丝、水热、溶剂热等）以及材料在除氟中的应用现状。在应用方面，介绍了不同因素对除氟能力的影响。最后，针对目前存在的问题提出了解决方案。然而，将其应用于工业大规模使用，需要各种研究人员的不断探索，使理论效果转化为实际效果，从而改善我们赖以生存的环境。
