The invention discloses a preparation method of an acrylic fiber-based photocatalytic material. ZIF-8 with adsorption and photocatalytic properties is grown on the acrylic fiber in situ, and then further oxidized to obtain an acrylic fiber-based photocatalytic material that has good adsorption performance and can be catalyzed and decomposed under visible light. Functional materials for dyes, used for decolorization of printing and dyeing wastewater. The macromolecules of acrylic fibers are in an irregular helical conformation without strict crystal regions, and the molecules contain acidic groups, which are beneficial to the growth of ZIF-8 on fibers. After pre-oxidation, acrylic fiber has excellent thermal conductivity, wear resistance and chemical stability, and has a long service life in the process of wastewater treatment. |
