Embodiment 1

[0029] Example 1 Preparation of MIL-101:

[0030] 1.33g (4.90mmol) FeCl 3 ·6H 2 O was dissolved in DMF (50mL), and 0.41g H 2 bdc (2.48 mmol) was added to the brown solution and stirred at room temperature for 10 minutes. The resulting mixture was divided into 10 portions and transferred to a 20 mL autoclave and heated at 383 K for 24 hours. After slow cooling to ambient temperature, the brown powder was centrifuged and washed thoroughly with distilled water and DMF. The product was dried under vacuum at 353K.

Embodiment 2

[0031] Example 2 Preparation of H 3 PMo 12 o 40 @MIL-101(Fe), abbreviated as PM

[0032] (1) 1.33g (4.90mmol) FeCl 3 ·6H 2 O was dissolved in DMF (50mL), and 0.41g H 2 bdc (2.48 mmol) was added to the brown solution and stirred at room temperature for 10 minutes.

[0033] (2) Add 0.2g H 3 PMo 12 o 40 Add in the mixture obtained in step (1) and stir for 0.5 hour;

[0034] (3) The mixture obtained in step (2) was transferred to an autoclave and heated at 383K for 24 hours; after cooling slowly to ambient temperature, the solid powder was separated and washed thoroughly with distilled water and DMF.

[0035] (4) Place the product obtained in step (3) under vacuum and dry at 353K to obtain the target product PM

Embodiment 3

[0036] Example 3 Preparation of PMo 11 VO 40 @MIL-101(Fe), abbreviated as PMV

[0037] (1) 1.33g (4.9mmol) FeCl 3 ·6H 2 O was dissolved in DMF (50mL), and 0.41g H 2 bdc (2.48 mmol) was added to the brown solution and stirred at room temperature for 10 minutes.

[0038] (2) Add 0.2g H 4 PMo 11 VO 40 Add in the mixture obtained in step (1) and stir for 0.5 hour;

[0039] (3) The mixture obtained in step (2) was transferred to an autoclave and heated at 383K for 24 hours; after cooling slowly to ambient temperature, the solid powder was separated and washed thoroughly with distilled water and DMF.

[0040] (4) Place the product obtained in step (3) under vacuum and dry at 353K to obtain the target product PMV

Abstract

The invention belongs to the technical field of materials, and in particular relates to a polyacid-based metal-organic framework material which can be used to adsorb antibiotics, a preparation method and application thereof. The polyacid-based metal-organic framework material that can be used to adsorb antibiotics is prepared according to the method comprising the following steps: (1) preparing a mixed solution including metal ions and organic ligands, and stirring for 0.1-12h; (2) adding to step (1) ) adding Keggin-type polyacids to the resulting mixed solution, and hydrothermally reacting to obtain the polyacid-based metal-organic framework material; (3) washing and drying the polyacid-based metal-organic framework material obtained in the step (2); (4) The polyacid-based metal-organic framework material is activated to remove water molecules in the metal-organic framework material, and the polyacid-based metal-organic framework material that can be used to adsorb antibiotics is obtained. The polyacid-based metal-organic framework material that can be used to adsorb antibiotics has good antibiotic adsorption performance.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a polyacid-based metal-organic framework material which can be used to adsorb antibiotics, a preparation method and application thereof. Background technique [0002] In the past 20 years, with the rapid development of animal husbandry and aquaculture, veterinary drug antibiotics have been widely used for their efficient prevention and treatment of animal diseases and promotion of animal growth. The production and usage of antibiotics in my country currently ranks second in the world in terms of antibiotics. However, during use, only part of the antibiotics are absorbed and metabolized by the passive body, and more than 80% of the antibiotics are still excreted in the active form (parent or metabolites) with the feces and urine, causing serious damage to the ecosystem and human health. great harm. [0003] Therefore, controlling and reducing the residues of antibi...
