Progress of Covalent Organic Frameworks in Iodine Capture
With the development of the nuclear industry, radioactive iodine was identified as one of the most hazardous nuclear wastes. Radioactive iodine capture also plays an important role in reducing the contamination of nuclear wastewater. Covalent organic frameworks (COFs), a crystalline porous organic material formed by covalent bond connection, are considered an ideal candidate for iodine capture materials for their large specific surface area, regular pore structure and high chemical stability. COFs are considered as ideal iodine trapping materials due to their structural characteristics and the fact that the adsorption sites of COFs are easily occupied by iodine molecules. This paper mainly reviews the progress of COFs with periodic porous structure and tunable functions in the field of iodine capture. Firstly, the recent progress in iodine capture of imine bonded COFs was briefly reviewed. Secondly, iodine capture capacity of compound COFs and ionic COFs are discussed. Finally, the potential of efficient iodine capture COFs to scale and the future development of this field.
