| titleOfInvention | A kind of microporous membrane material, preparation method and application thereof |
| abstract | The invention discloses a microporous filter membrane material, a preparation method and application thereof, and belongs to the technical field of microporous filter membrane materials. The microporous filter membrane material is prepared from the hydrolyzed polyamide filter membrane obtained by hydrolysis of the polyamide filter membrane after amidation reaction to form a benzoyl group. It can effectively retain particulate impurities in the sample solution while avoiding the adsorption of carboxyl or hydroxyl group-containing target compounds by traditional polyamide microfiltration membranes in water-methanol or water-acetonitrile solution systems, expanding the traditional polyamide microporous filtration membrane. The scope of application of the membrane. It can be used to prepare microporous membranes, especially syringe-type microporous membranes. The above-mentioned microporous filter membrane material and the corresponding microporous filter membrane can be used to filter sample solutions, especially sample solutions in food safety testing, which can improve the accuracy of testing results. |
