Covalent organic frameworks (COFs) are an emerging class of new porous crystalline polymers materials having robust framework, outstanding structural regularity, highly ordered aperture size, inherent porosity, and chemical stability with designer properties, making them an ideal material for adsorbing a variety of contaminants from water bodies. Presented study focusses on the current advances and progress of pristine COFs as well as COFs based composites as an emerging substitute for the adsorption and removal of a variety of pollutants including water desalination technique, heavy metals, pharmaceuticals, dyes and organic pollutants. The absorption capabilities of COFs-derived architecture are evaluated and equated with those of other commonly used adsorbents. The interaction between sorption ability and structural property as well as some regularly utilized ways to improve the adsorption performance of COFs-based materials are also reviewed. Finally, perspective and a summary about the challenges and opportunities of COFs and COFs-derived materials are discussed to deliver some exciting data for fabricating and designing of COFs and COFs-derived materials for remediation of environmental pollutants.
共价有机框架（COFs）是一类新兴的新型多孔结晶聚合物材料，具有坚固的框架、出色的结构规整性、高度有序的孔径尺寸、固有孔隙率和化学稳定性以及可设计的特性，使其成为从水体中吸附各种污染物的理想材料。本研究重点关注原始COFs以及基于COFs的复合材料作为一种新兴替代品在吸附和去除包括水淡化技术、重金属、药物、染料和有机污染物在内的各种污染物方面的当前进展。评估了源自COFs的结构的吸附能力，并将其与其他常用吸附剂的吸附能力进行了比较。还综述了吸附能力与结构性能之间的相互作用以及一些常用于提高基于COFs的材料吸附性能的方法。最后，讨论了关于COFs及其衍生材料面临的挑战和机遇的展望和总结，为制造和设计用于修复环境污染物的COFs及其衍生材料提供一些令人兴奋的数据。
