1results about How to "Improve adsorption speed" patented technology

The application provides a binary ionic liquid fiber membrane, a preparation method and application in adsorption of palladium, and belongs to the technical field of adsorption materials, and comprises the following steps: mixing dichloromethane and acetic acid to obtain a first solution; dissolving cellulose acetate, a first ionic liquid and a second ionic liquid in the first solution to obtain a second solution; the first ionic liquid and the second ionic liquid are alkenyl imidazole salts with different length alkyl side chain molecular structures; adding N,N'-methylene bisacrylamide and benzoyl peroxide into the second solution, heating, stirring and warming to obtain a third solution; performing high-pressure electrospinning on the third solution to obtain a binary ionic liquid fiber membrane; or performing irradiation on the second solution after high-pressure electrospinning to obtain a binary ionic liquid fiber membrane. The binary ionic liquid fiber membrane prepared by the application can efficiently and selectively adsorb and recover palladium from a complex acidic solution, and has the advantages of faster adsorption speed, better selectivity and better salt resistance.
