Covalent organic frameworks (COFs) is made by covalent bonding of light elements, such as carbon, oxygen, nitrogen, boron and hydrogen, which can be flexibly synthesized as a porous material with low density, high permanent porosity and controllable sizes. This mini-review outlined the current understandings of mechanisms to yield a chemically stable COF and the use of these COFs to be adsorbents for removing adsorbates from waters. The research and development need to apply the COFs as industrial adsorbetns was discussed.

化学稳定的共价有机骨架作为水溶液中的吸附剂：综述

共价有机骨架（COF）是通过轻质元素（例如碳，氧，氮，硼和氢）的共价键合制成的，这些元素可以灵活地合成为低密度，高永久孔隙率和可控制尺寸的多孔材料。这份小型综述概述了当前对产生化学稳定的COF的机理的理解，并概述了使用这些COF作为吸附剂从水中去除吸附物的方法。讨论了将COF用作工业吸附素的研究和开发需求。
