Document Type and Number:
WIPO Patent Application WO/2021/212533
Kind Code:
A1
Abstract:
Provided are a preparation method for a porous metal organic framework compound, a compound prepared by the method, and an application of the compound in adsorbing a radioactive gas. The preparation method comprises: mixing zinc nitrate hexahydrate, an imidazole organic ligand, and an N,N-dimethylformamide solvent to obtain a mixed solution, and performing heating treatment on the mixed solution to obtain the porous metal organic framework compound, wherein the temperature of heating treatment is 60-100°C, the time of heating treatment is 60-84 h, the imidazole organic ligand is a mixture of benzimidazole and imidazole, and the molar ratio of benzimidazole to imidazole is (1:3)-(5:1). The porous metal organic framework compound prepared by the method has an efficient and specific adsorption effect to the radioactive gas, particularly to a radon gas.
