Method used for adsorbing iodine with covalent organic framework material

The invention discloses a method used for adsorbing iodine with a covalent organic framework material. According to the method, the covalent organic framework material is used for iodine adsorption, material thermal stability after iodine adsorption is evaluated. The covalent organic framework material is taken as an iodine adsorbent for the first time, and high efficiency iodine adsorption is realized at mild conditions.
