Abstract
A method of preparing a fibrous polymeric adsorption material includes preparing a linear polymer yarn from a linear polymer via melt-blow spinning, the linear polymer having a molecular weight of 15,000 to 20,000 g/mol; treating the linear polymer yarn with a crosslinking agent and a porogen agent; and heating the treated linear polymer yarn at 130 to 150° C. for 25 to 35 seconds to obtain the fibrous polymeric adsorption material. The fibrous polymeric adsorption material includes fibers with a diameter of 4 to 6 microns. The crosslinking agent is in an amount of 1 to 3 weight % of the linear polymer. The crosslinking agent is a diacrylate ester compound having Formula J1, J2 or J3. The porogen agent is in an amount of about 1 weight % of the fibrous polymeric adsorption material.
