Embodiment 1

[0054] Embodiment 1 (preparation of bio-MOF-1)

[0055]

[0056]

[0057] The above-mentioned raw materials, 13.5ml of N,N-dimethylformamide (DMF) as a solvent, and 1ml of water were sequentially put into a 20ml autoclave lined with polytetrafluoroethylene. Heat at 130°C for 24 hours. And gradually cooled to room temperature to obtain rod-shaped colorless crystals. The crystals were rinsed three times with DMF (3 ml). Then dry under argon atmosphere for 30 minutes.

[0058] The resulting products were then characterized by X-ray powder diffraction measurements. The resulting product exhibits the figure 1 The X-ray powder diffraction pattern shown is consistent with that of bio-MOF-1.

Embodiment 2

[0059] Embodiment 2 (ion exchange of bio-MOF-1)

[0060] Weigh 0.35g of bio-MOF-1 obtained in Example 1 and add it to 20ml of 0.1mol / L lithium nitrate in EtOH / H2O (15ml / 5ml) solution, soak at room temperature for 48h, and change the fresh solution every 24 hours , and then rinsed with ethanol several times to wash away the lithium nitrate on the surface, and dried naturally to obtain the Li ion-exchanged bio-MOF-1.

[0061] The purification method involved in the present invention uses metal-organic framework materials to absorb smell, taste, chroma, chlorinated organic substances, pesticides, radioactive organic substances and other artificially synthesized organic substances in water to purify water bodies; and by means of ion exchange, The hardness of water is reduced, which can meet the special use and treatment effect requirements of tap water purification process for water purification materials.

Abstract

The invention provides a method for using a metal-organic framework material to purify water, exchange ions with water or magnetize water and relates to the technical field of water treatment. The invention relates to a method for using the metal-organic framework material to purify water, exchange ions with water or magnetize water, to purity water and exchange ions with water, to purify water and magnetize water, to exchange ions with water and magnetize water, or to purify water, exchange ions with water and magnetize water. The metal-organic framework material contains pores, at least one metal ion and at least one organic compound, wherein the organic compound is at least bidentate and is bound (preferably, coordinately bound) with the metal ions. The invention also relates to a water purifier which contains the metal-organic framework material and is used for realizing the purpose. The method and the water purifier provided by the invention can be used for absorbing harmful substances in water, such as chlorine, peculiar smell, heterochrosis, peculiar odor matters, particle impurities, organic matters, chemical matters, heavy metal ions, and the like, achieving a function of purifying water and reducing the hardness of water. The metal-organic framework material contains ferromagnetic metal ions, thereby being capable of endowing water with magnetism.

Description

technical field [0001] The invention relates to the technical field including water treatment, in particular to water purifier technology. In particular, the present invention relates to a method of purifying, or ion-exchanging, or magnetizing, or purifying and ion-exchanging, or purifying and magnetizing, or ion-exchanging and magnetizing, or purifying, ion-exchanging and magnetizing a water using a metal-organic framework material, which The framework material comprises pores and at least one metal ion and at least one at least bicoordinate organic compound bound, preferably coordinate bound, to said metal ion and relates to a device comprising the above defined material. Background technique [0002] Water is an indispensable substance for people's life, and it can even be said to be one of the necessary conditions for human beings from bottom to top. However, most of the water bodies in China are seriously polluted at present, and the traditional tap water treatment met...
