Title:
PREPARATION METHOD FOR MAGNETIC COVALENT ORGANIC FRAMEWORK, MTFBD-PPD, PRODUCT AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/188209
Kind Code:
A1
Abstract:
A preparation method for a magnetic covalent organic framework, mTFBD-PPD, a product and the use thereof, which belong to the technical field of preparation of a toxin adsorbent. The preparation method comprises: dissolving 3,3',5,5'-tetraaldehyde-4,4'-dihydroxybiphenyl and an alkali in water to obtain a solution; dispersing p-phenylenediamine and magnetic nanoparticles in an organic solvent to obtain a dispersion; and mixing the solution with the dispersion, and reacting same to obtain a magnetic covalent organic framework, mTFBD-PPD. The new adsorbent, mTFBD-PPD, which is prepared by combining a covalent organic framework material with magnetic nanoparticles, has the characteristics of a large specific surface area, good thermal stability, a strong selectivity, being capable of rapid separation, being reusable, etc.; and same can effectively improve the adsorption rate during the use thereof in the adsorption of diarrhetic shellfish toxins.
