摘要:

目前我国水环境以及空气面临着严峻的污染形势,许多危害人身体健康的污染物亟待治理。 金属有机骨架作为目前新兴的多孔材料,具有高孔隙率、高比表面积、结构可调性以及不饱和金属位点等特点。 这使得金属有机骨架材料具有一定的环境污染物去除能力。 围绕对苯二甲酸铬金属有机骨架材料(MIL-101)及其功能化修饰的改性材料的结构信息展开,总结了材料的主要合成方法,对功能化修饰的方法和原理进行分析,重点分析了这种材料在环境污染物去除等方面的应用研究进展,包括它在重金属离子、农药、抗生素、有机染料、碘离子等污染物的吸附处理领域的应用, 以及在污染物的监测和环境风险预警方面的应用潜力。 指出了材料在制备成本、反复利用次数、污染物后续处理等方面仍然存在的问题。

Abstract:

The pollution issues of water and air in China currently become severe. Many pollutants that endanger people's health are urgently needed to be treated. As a kind of emerging porous material, the metal-organic framework has many applications in the treatment processes of pollutants. This paper introduces the structural information of chromium terephthalate metal organic framework material (MIL-101) and its functionally modified materials. The main synthesis methods of this material are summarized as well. The research progress of the application of this material in the environmental pollutant removal is analyzed, including the adsorption treatment of heavy metal ions, pesticides, antibiotics, organic dyes and iodide ions, etc. It also has the potential of monitoring pollutants and risk warning. This paper also points out some problems which are still pending.

Key words: chromium terephthalate metal organic framework material, porous material, functional modification, pollutant removal
