Embodiment

[0024] 1. Add 10 grams of polyethersulfone, 1 gram of polyethylene glycol, and 79 grams of N-methylpyrrolidone into a container, and stir at 80° C. for 4 hours to obtain a polymer solution. Slowly add 10 grams of activated carbon powder into the polymer solution to prepare a mixed suspension. The above mixed suspension was injected into water through a 1.2 mm injection needle and stirred at a speed of 100 rpm. Microspheres with a diameter of 2.7 mm were placed in deionized water for 24 hours, and the deionized water was replaced several times to remove the residual solvent to make an adsorption column. The removal amount of bisphenol A was 50 mg / g; The amount is 25mg / g; the removal amount of metal copper ions is 3.5mg / g.

[0025] 2. Add 8 grams of polysulfone, 0.5 grams of polyvinylpyrrolidone, and 79.5 grams of dimethylformamide into the container, and stir at 75° C. for 6 hours to obtain a polymer solution. Slowly add 12 grams of activated carbon powder into the polymer so...

Abstract

The disclosed synthesized macromolecular and active carbon hybridized porous microballoon is characteristic in that: preparing macromolecular liquid with 5~15 macromolecule, 0.01~10 additive, and 40~90 solvent; adding 5~50 powder active carbon into said liquid to obtain mixed suspending liquid; injecting said liquid into nonsolvent of macromolecular compound, stirring to prepare the final product. Wherein, the diameter is 2~4mm, the porosity is 15~90%, and active carbon takes up 25~90%. The adsorption column made from this product can remove hormone toxin, liver and heavy metal ion with removal quantity as 2~80mg / g, 5~50mg / g and 1~30mg / g, respectively.

Description

technical field [0001] The invention relates to a synthetic polymer and active carbon hybrid porous microsphere and its preparation method and application. It belongs to the field of modified functional materials. Background technique [0002] Activated carbon is a broad-spectrum adsorbent, which has a good removal effect on various substances due to its large specific surface area. However, activated carbon is generally a very fine powder substance, and it is difficult to separate it from the liquid when it is directly applied. Especially when used in hemoperfusion, or in the treatment of beverages and drinking water, it will directly affect the quality and quantity of treatment, and even bring some negative effects. Therefore, during hemoperfusion, the surface of activated carbon is covered with a film, which improves the blood compatibility of the material and prevents the dissolution of soluble small molecule particles. Activated charcoal also has great advantages in ...
