Title:
CATIONIC METAL-ORGANIC FRAMEWORK MEMBRANE MATERIAL AND PREPARATION METHOD AND APPLICATION
Document Type and Number:
WIPO Patent Application WO/2021/051849
Kind Code:
A1
Abstract:
Provided are a cationic metal-organic framework membrane material and a preparation method and an application. The preparation method comprises: dispersing a polymer and UiO-66-NH2 into a solvent and mixing uniformly, laying the uniformly mixed liquid and removing the solvent to obtain a UiO-66-NH2 membrane, using methyl trifluoromethanesulfonate to react with the UiO-66-NH2 membrane to implement quaternary amination of the amino group of the UiO-66-NH2 membrane, and then soaking the UiO-66-NMe3
+CF3SO3
- membrane after quaternary amination in a hydrochloric acid solution to obtain a UiO-66-NMe3
+Cl- membrane. The provided cationic metal-organic framework membrane material retains the highly efficient selective adsorption properties of the metal-organic framework material, also facilitates separation from an aqueous solution, and has a good application prospect for the removal and enrichment of anionic pollutants in water.
