Grafting of Acrylic Membrane Prepared from Fibers Waste for Dyes Removal: Methylene Blue and Congo Red

Dyes are a type of pollutant that have been discharged into water streams by various industries and had harmful effects on the environment human health. Therefore, present work was directed to recycle acrylic fibers waste be used as an adsorbent exclude dyes such methylene blue (MB) Congo red (CR) from dyes-polluted wastewater. Acrylic converted membrane followed chemical grafting with p-phenylenediamine monomer form functional modified membranes. Afterwards, some characterization analyses; Fourier transform-infrared, scanning electron microscope, swelling behavior, porosity properties were performed for fiber grafted (AFGM). For obtaining best conditions permit highest adsorption capacity AFGM, preliminary experiments general full factorial design displayed. Langmuir, Freundlich isotherms kinetic studies evaluations applied. Results revealed that, capacities AFGM 61% Methylene 86% stated high affinity anionic dyes. The reusability membranes in different cycles 3Rs processes “Removal, Recovery, Re-use” indicated efficiency wastewater treatment.
