摘要
金属有机框架(MOFs)是具有多孔纳米结构的新型膜改性材料,因其复杂的几何形状、可调节的窗口尺寸、高的孔隙率以及优异的水热稳定性等特性,被广泛应用于废水处理,如水处理膜技术。本文以几种常用的MOFs纳米粒子为主,简述了MOFs独特的结构特点。介绍了MOFs改性膜在不同废水处理领域的最新应用进展,以不同MOFs纳米粒子改性膜的制备方法、分离效果和可能的分离机制等方面,分析了其在脱盐、重金属去除、染料去除和油/水分离等领域的重要作用。提出了MOFs改性膜在废水处理领域仍需解决的关键问题,并对MOFs改性膜的未来研究进行了展望。
Metal-organic framework(MOFs)is a new membrane modified material with porous nano-structure,which is widely used in wastewater treatment,such as the membrane technology for water treatment,because of its complex geometry,adjustable window size,high porosity and excellent hydrothermal stability.In this paper,several commonly used MOFs nanoparticles are introduced,and the unique structural characteristics of MOFs are briefly described.The latest application progress of MOFs modified membranes in different wastewater treatment fields is reviewed.By introducing the preparation methods,separation effects and possible separation mechanisms of different MOFs nano-particle modified membranes,their important roles in desalination,heavy metal removal,dye removal and oil/water separation are analyzed.The key problems that need to be solved in the field of wastewater treatment by MOFs modified membrane are put forward,in addition,the future research of MOFs modified membranes is also prospected.
