Effective Dye Removal by Acrylic-Based Membrane Constructed from Textile Fibers Waste

Abstract The good mechanical and chemical stability of textile acrylic fibers waste has promoted its candidacy for fabricating low cost membranes wastewater treatment. In this work, nanofiltration based on the were successfully prepared using phase inversion technique. First, membrane solutions with different concentrations (16, 18, 20, 22%) (AF) in dimethyl formamide (DMF) prepared. Evaluation performance terms water flux dyes (Congo red methylene blue) rejection was investigated. Nanofiltration obtained at 20% polymer concentration. This modified by adding ratios (3, 5, 10 wt%) polyvinyl pyrrolidone (PVP) to enhance performance. Characterization explored attenuated total reflectance-Fourier transform infrared (ATR-FTIR), thermogravimetric analysis, scanning electron microscopy (SEM), contact angle, swelling properties. results show that addition 5% PVP elevated a high equal 320 L/m 2 /h complete removal Congo 90% blue pressure (3 bar). molecular weight cutoff produced found be 319.85 Dalton. Moreover, effect dye concentration applied studied. entire work presented an optimization procedure obtaining standalone materials (textile fiber waste).
