Exploration of electrospinning hemp/polyacrylonitrile composite fiber membrane and dye adsorption capabilities

Abstract Textile printing and dyeing wastewater has complex water quality and causes great harm. As a common pollutant, the cationic methylene blue dye is harmful to health. Therefore, adsorption technology plays a crucial role in wastewater treatment. To study the application of hemp/polyacrylonitrile nanocomposite fiber membranes in dye adsorption, this study employed electrospinning technology. This study used electrospinning to prepare hemp/polyacrylonitrile nanocomposite fiber membranes for dye adsorption. Hemp fibers were dissolved in LiCl/DMAc, blended with polyacrylonitrile solution, and electrospun after
