Preparation and Characterization of Poly(acrylonitrile-co-vinyl Acetate) Hollow Fiber Membranes for Wastewater Treatment

Year: 2025

Type: article

Abstract: The hollow fiber membranes of poly(acrylonitrile-co-vinyl acetate) were fabricated by the dry jet wet spinning method and used as membranes to separate disperse dyes from an aqueous solution. The effect of the coagulant on the mechanical properties of the hollow fibers and dye removal were investigated. The morphology and porosity of the hollow fibers were determined. The results showed that the addition of a solvent to the coagulants leads to a decrease in the permeability. The tensile strength of the membranes increased with an increase in the amount of a solvent in the coagulant. The hollow fibers spun with a higher solvent content showed lower hydraulic permeability and higher dye removal efficiency.
