Embodiment 1

[0032] (1) Preparation of carbon foam (CF)

[0033] Mix 3mL formaldehyde solution and 1.5mL melamine, then add 2g triethanolamine, then vigorously stir at 50°C and 500rpm for 20min, and then obtain a prepolymer solution. Then 6 mL of toluene solution was gradually added dropwise to the pre-poly solution, and then stirred at 1000 rpm for 2 min. The resulting emulsion was then polymerized at 60°C for 3 hours. Then dry it under vacuum at 50°C for 12 hours. 50 mg of the obtained high internal phase emulsion were fired in a tube furnace for 2 hours, and heated to 400, 500, and 600 degrees at 5°C / min to obtain CF-400, CF-500, and CF-600.

[0034] (2) Preparation of CF-500-B-MOF

[0035] First, put 50mg of CF-500 into 0.1g of zinc nitrate hexahydrate solution, and stir a mixed solution (v:v, 1:1) of 5mL of ethanol and water for 6 hours in a polytetrafluoroethylene reactor . Then add 40 mg of 3,5-dicarboxyphenylboronic acid (BBDC) and 40 mg of terephthalic acid (H 2 BDC) was rea...

Embodiment 2

[0037] (1) Preparation of carbon foam (CF)

[0038] 4mL of formaldehyde solution and 2mL of melamine were mixed, then 3g of triethanolamine was added, and then vigorously stirred at 500rpm at 70°C for 40min to obtain a prepolymer solution. Then gradually add 10 mL of toluene solution dropwise to the pre-poly solution, and then stir at 1000 rpm for 2 min. The resulting emulsion was then polymerized at 80°C for 5 hours. Then dry it under vacuum at 70 degrees for 48 hours. 50 mg of the obtained high internal phase emulsion were fired in a tube furnace for 2 hours, and heated to 400, 500, and 600 degrees at 5°C / min to obtain CF-400, CF-500, and CF-600.

[0039] (2) Preparation of CF-500-B-MOF

[0040] First, put 100mg of CF-500 into 0.2g of zinc nitrate hexahydrate solution and mix it with 15mL of ethanol and water (v:v, 1:1) and stir for 24 hours in a polytetrafluoroethylene reactor . Then add 50 mg of 3,5-dicarboxyphenylboronic acid (BBDC) and 50 mg of terephthalic acid (H ...

Embodiment 3

[0042] (1) Preparation of carbon foam (CF)

[0043] Mix 3.5mL formaldehyde solution and 2mL melamine, then add 2.5g triethanolamine, then stir vigorously at 60°C and 500rpm for 30min, and then obtain the prepolymer solution. Then 8 mL of toluene solution was gradually added dropwise into the pre-poly solution, and then stirred at 1000 rpm for 2 min. The resulting emulsion was then polymerized at 70°C for 4 hours. Then dry it under vacuum at 60°C for 24 hours. 50 mg of the obtained high internal phase emulsion were fired in a tube furnace for 2 hours, and heated to 400, 500, and 600 degrees at 5°C / min to obtain CF-400, CF-500, and CF-600.

Abstract

The invention belongs to the field of technologies for preparing environment functional materials, and particularly discloses a method for preparing carbon foam adsorbents modified by phenylboronic acid type metal organic framework materials. The method includes synthesizing high-temperature-resistant high-internal-phase materials; calcining the high-temperature-resistant high-internal-phase materials in a tube furnace to obtain carbon foam; soaking carbon foam materials in zinc ion solution; adding an organic ligand (terephthalic acid) and a ligand fragment (3, 5-dicarboxy phenylboronic acid) into the zinc ion solution and carrying out a series of treatment to obtain the adsorbents; applying the adsorbents to selectively recognizing and separating luteolin. The method has the advantages that emulsion imprinted polymer micro-spheres prepared by the aid of the method are high in heat stability, the luteolin can be efficiently adsorbed, and the carbon foam adsorbents have acid-alkali control release performance.

Description

Technical field: [0001] The invention belongs to the technical field of preparation of environmental functional materials, and relates to a method for modifying carbon foam adsorbents with phenylboronic acid-type metal-organic framework materials. Background technique [0002] Macroporous materials have attracted extensive attention due to their remarkable compression resistance and have been used in many fields, such as catalysts, tissue engineering, adsorption and separation, etc.; the traditional method of preparing such macroporous materials is to polymerize them with surfactants. High internal phase emulsion (High Internal Phase Emulsion, HIPE), also known as high-concentration emulsion, is an emulsion with a dispersed phase volume fraction greater than 74.05%. [0003] Metal-organic frameworks are three-dimensional porous materials formed by the self-assembly of organic ligands and metal ions or clusters through coordination bonds. Due to its huge specific surface are...
