“…Simultaneously, the elongation of adsorbents decreased gradually. After researching the literature [ 43 , 44 , 45 , 46 , 47 ], we think that although the addition of cyclodextrin leads to a decrease in the elongation at break and tensile strength, the adsorbent still shows good mechanical properties.…”

In this paper, environmentally friendly gelatin/β-cyclodextrin (β-CD) composite fiber adsorbents prepared by electrospinning were used for the removal of dyes from wastewater. Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and a universal materials tester were employed to characterize the internal structures, surface morphologies and mechanical strength of the composite fiber adsorbents. Additionally, the fiber was evaluated as an adsorbent for the removal of methylene blue (MB) from aqueous solution. The effects of the raw material ratio, pH, temperature, concentration and adsorption time were studied. The results show that the gelatin/β-CD composite fiber adsorbents possess excellent mechanical strength and high adsorption efficiency for MB. The adsorption equilibrium and adsorption kinetics are well-described by the Langmuir isotherm model and the pseudo-second-order kinetic model, respectively. The theoretical maximum adsorption capacity is 47.4 mg·g−1. Additionally, after nine successive desorption-adsorption cycles, the removal rate is still over 70%. Moreover, the gelatin/β-CD composite fiber adsorbents exhibit excellent adsorption capability for basic fuchsin, gentian violet, brilliant blue R and malachite green dyes. Therefore, owing to the characteristics of degradability, low cost and high-efficiency, the gelatin/β-CD composite fiber can be used as an efficient adsorbent for the removal of dyes from wastewater.

“…The efficiency of bio‐based nanofibers (≈55 mg g −1 ) is comparable to that of commercial montomorillonite nanoclay adsorbent (≈57 mg g −1 ) for the removal of Cu(II) ions and could also achieve ≈90% recovery after five cycles. With this regard, the multistep oxidization of cellulose membrane was also investigated by Zeid and coworkers to generate tricarboxylic groups on the surface of the fiber for evaluating its adsorption capacity and found that the nanofibers exhibited capacity of 92.23 mg g −1 for adsorption of Cu(II) ions as shown in Figure which is relatively higher than oxidized cellulose nanofibers produced by single step . The potential of using nanofibers in the removal of Pb(II) and Cd(II) ions was unleased by complexing PVA and chitosan to attain uniformity in fiber morphology.…”

“…The factors such as pH, temperature, and surface charge density affect the interaction process. Modifications such as deacetylation, (2,2,6,6‐tetramethylpiperidin‐1‐yl)oxyl (TEMPO)‐mediated oxidation and hydrolysis on the fibers also had an impact on adsorption process . In few cases, the overall shape of the nanofibrous adsorbent affect the behavior, especially, the spherical shape accommodated more molecules on the surface due to high area .…”

Studies involving bio‐based nanofibers are well utilized in the field of energy, catalysis, electronics, and environmental science. In this review, the importance of utilizing bio‐based materials for the development and optimization of multiplexed nanofibers and the modifications adopted to overcome the drawbacks of conventional electro‐spinning to facilitate better production rates, enhanced adsorption, and its potential in removing heavy metal ions, dyes, and other contaminants polluting the environment are highlighted. This work provides the readers the ability to understand the complexity in fabrication of bio‐based nanofibers focusing primarily on chitosan, cellulose, and protein‐based nanofibers and their mechanism toward quenching/degradation of water contaminants. In addition, it also provides the advantages of using bio‐based materials over synthetic materials for the development of nanofibers.

“…Researchers have studied the removal of harmful heavy metals using biopolymer-based adsorbents, for instance, cellulose. Abou-Zeid et al [ 22 ] employed tetramethylpiperidine oxide oxidation with and without polyamide-amine-epichlorohydrin crosslinker to form 2,3,6-tricarboxy cellulose nanofiber as a bio-adsorbent, which they used for the treatment of water containing calcium, lead, and copper particles. In another study, phosphoric acid was used to functionalize cellulose nanofibers with a phosphate group for the removal of copper particles from water [ 23 ].…”

The objective of this work was to fabricate modified cellulose nanofibers (CNFs) for the removal of heavy metal ions (Cd2+ and Pb2+) from wastewater. Cellulose was modified with 2-hydroxyethyl methacrylate (HEMA) via grafting copolymerization using the microwave-assisted technique in the presence of ceric ammonium nitrate (CAN) as an initiator. Prepared cellulose-graft-(2-hydroxyethyl methacrylate) (HEMA/C) copolymers were characterized using Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). Different factors affecting the graft yield, such as irradiation time, monomer concentrations, and initiator concentrations, were investigated. Furthermore, cellulose-graft-(2-hydroxyethyl methacrylate) copolymer nanofibers (HEMA/CNF) were fabricated by electrospinning using N,N-dimethylacetamide-LiCl as a solvent. Electrospun nanofiber copolymers were characterized using SEM and thermogravimetric analysis (TGA). Operating parameters, including time, starting metal concentrations, and adsorbent concentration, were analyzed at a pH of 5.6 for the two metal ions. The best-fit model of adsorption energy was the pseudo-second-order model, and adsorption isotherms at equilibrium were well described by the Langmuir and Freundlich models. The negative values of ΔG and positive values of ΔH and ΔS suggest that the adsorption of Cd2+ and Pb2+ ions onto electrospun HEMA/CNF is a spontaneous, endothermic, and favorable reaction.
