Advances in Covalent Organic Framework Materials and Application in Separation of Radionuclide Uranium
With the discharge of nuclear wastewater from the Fukushima nuclear power plant,water contamination caused by the radionuclide uranium will become a global problem.Among the various existing materials for separation and removal of uranium,covalent organic frameworks(COFs)are an emerging class of porous materials.Due to the advantages of large specific surface area,high stability,strong adsorption capacity,predictable structural composition,and controllable function,covalent organic frameworks(COFs)have become one of the more advanced separation materials in the field of water treatment,and have shown great potential in the separation of the radionuclide uranium.This paper reviews the recent progress in the synthesis of COF materials,their post-synthesis functionalization and their applications in separating radionuclide uranium from water.Finally,the opportunities and challenges of COF materials are summarized and outlooked,and some guiding information is provided for the design and preparation of COF materials for the removal of radionuclide uranium.
