Abstract

The invention relates to the technical field of iodine adsorption, in particular to a tetrathiafulvalene covalent organic framework material and a preparation method and application thereof. The structure of the tetrathiafulvalene covalent organic framework material is shown in the formula I. The tetrathiafulvalene covalent organic framework material can effectively improve the iodine adsorption rate, almost linearly increases within 10 hours and reaches saturation within 18 hours, the iodine adsorption rate is greatly improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of radionuclide-iodine adsorption, in particular to a tetrathiafulvalenyl covalent organic framework material and its preparation method and application. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] In recent years, nuclear energy has developed rapidly worldwide due to its cleanliness and high energy density. At the same time, during the treatment of nuclear power plant waste and other nuclear energy utilization, a large amount of radioactive substances are released into the underground environment. Due to their chemical and biological toxicity and strong radioactivity, the pollution hazards caused by ...
