Fabrication of Electrospun PVA-Aloe Vera Hybrid Nanofibers: Dye Removal Ability from Wastewater
摘要
Hybrid of polyvinyl alcohol and aloe vera gel (PVA@AVG) electrospun nanofiber composite has been developed by the electrospinning technique. AVG was used in 5% and 10% concentrations (w/v) to develop two adsorbent materials, named PVA@AVG5 and PVA@AVG10, respectively, with a fixed concentration of PVA, and glutaraldehyde (GA) as a crosslinker. The morphological structure and properties of developed adsorbent materials were characterized using several techniques, including SEM, EDAX, FT-IR, and XRD. PVA@AVG10 exhibited a high removal efficiency of 100% toward RhB dye in comparison with PVA@AVG5 under similar conditions. Sorption studies support its competency for pseudo-second-order (PSO) kinetics and Langmuir isotherm model with qmax of 119.76 and 277.7 mg.g−1 for PVA@AVG5 and PVA@AVG10, respectively. These results confirm the good candidacy and effectiveness of the prepared membrane, offering an encouraging solution to wastewater treatment.
