水中过量的磷和氟对环境和人体健康构成严重威胁,而金属有机框架化合物(MOFs)因其多孔性、高比表面积和可调节的化学性质,在水处理中显示出巨大潜力。详细讨论了铝基、稀土基和锆基MOFs在处理含氟和含磷废水中的吸附性能,并分析了吸附机理。同时,探讨了影响MOFs吸附效率的关键因素。最后,概述了MOFs在水处理中的最新进展,包括与其他材料的结合、功能化改性以及提高循环利用次数。尽管MOFs在研究中取得了突出进展,但在成本、大规模生产和长期稳定性等因素上仍面临挑战,未来的研究将更关注新型材料的设计、资源的循环利用以及实际应用中的优化。
Excess phosphorus and fluoride in water pose a serious threat to the environment and human health.Due to their porosity,high surface area,and tunable chemical properties,Metal-organic frameworks (MOFs) show great potential in water treatment.The article provided a detailed discussion on the adsorption performance of MOFs,including aluminum-based,rare earth-based,and zirconium-based MOFs,in treating wastewater contaminated with fluoride and phosphate,and analyzed the adsorption mechanisms.Additionally,the key factors affecting the adsorption efficiency of MOFs were explored.Finally,the latest progress in the application of MOFs in water treatment was summarized,including combination with other materials,functionalization modification,and improving the number of cycles.Although MOFs have made significant progress in research,they still face challenges such as cost,large-scale production,and long-term stability.Future research will focus more on the design of new materials,the recycling of resources,and optimization in practical applications.
