specific Embodiment approach 1

[0047] Embodiment 1: This embodiment is a bifunctional amorphous FeMn-MOF-74 nano flower material with 2,5-dihydroxyterephthalic acid as the organic ligand, anhydrous manganese chloride and anhydrous chloride The ferrous metal is a metal salt ligand, and it is prepared by a solvothermal method using N,N-dimethylformamide and absolute ethanol as solvents.

specific Embodiment approach 2

[0048] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the mass of the described anhydrous manganese chloride and the volume ratio of N,N-dimethylformamide are (0.2g~0.4g): 30mL; the volume ratio of the mass of the anhydrous ferrous chloride to N,N-dimethylformamide is (0.08g~0.1g): 30mL; the 2,5-dihydroxyterephthalic acid The volume ratio of the mass of N,N-dimethylformamide to N,N-dimethylformamide is (0.08g~0.1g):30mL; the volume ratio of the absolute ethanol to N,N-dimethylformamide is (1~3 ):30. Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0049] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the mass ratio of the anhydrous manganese chloride to N,N-dimethylformamide is 0.3g:30mL; The volume ratio of the quality of the anhydrous ferrous chloride to N,N-dimethylformamide is 0.09g:30mL; the quality of the 2,5-dihydroxyterephthalic acid to N,N-di The volume ratio of methylformamide is 0.09g:30mL; the volume ratio of absolute ethanol to N,N-dimethylformamide is 2:30. Other steps are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to a double-functional amorphous FeMn-MOF-74 (ferromanganese-metal organic framework-74) nanoflower material and a preparation method and application, and relates to a nanometermaterial and a preparation method and application, which aim at solving the problem of low adsorption capacity of existing MOF-based adsorbent to As(III). The double-functional amorphous FeMn-MOF-74 nanoflower material is prepared by taking 2,5-dihydroxy terephthalic acid as an organic ligand, anhydrous manganese chloride and anhydrous ferrous chloride as metal salt ligands, and N,N-dimethyl formamide and anhydrous ethanol as solvents through a solvothermal method. The preparation method comprises the following steps of 1, preparation of a mixed solution; 2, solvothermal reaction; 3, cleaningand drying. The double-functional amorphous FeMn-MOF-74 nanoflower material is used for removing poisonous metals in water, and oxidizing the poisonous metals in the water. The preparation method canbe used for preparing the double-functional amorphous FeMn-MOF-74 nanoflower material.

Description

technical field [0001] The invention relates to a nanometer material, a preparation method and an application. Background technique [0002] Arsenic pollution is one of the most serious water environmental pollution problems in modern society. At least 20 countries and regions in the world are suffering from arsenic pollution, such as China, India, Bangladesh, Vietnam, Thailand in Asia, Argentina, Chile, Brazil, Mexico in South America, Germany, Spain, In the United Kingdom, Canada and the United States in North America, there have been reports of acute or chronic poisoning caused by drinking water contaminated by arsenic. Taking China as an example, the more serious arsenic pollution incidents in recent years include arsenic pollution in Yangzonghai, Yunnan, arsenic pollution in Yueyang, Hunan, and arsenic pollution in Minquan, Henan. The sources of arsenic pollution in water bodies include human factors and natural factors, which are mainly divided into the following cat...
