“…[114] Similarly, electrospun fibers were prepared by deacetylated cellulose acetate and polydopamine for the adsorption of methylene blue. [115] It is worth mentioning the swellable electrospun fibers performed promisingly in terms of swelling capacity (6942.2%) [116] and adsorption capacities (1834.97 mg g −1 ) for methylene blue.…”

The use of unmodified and chemically treated natural fibers for water remediation (removal of chemical residues/oil spills and organic wastewater from water) is a significant and low-cost strategy to reduce the contamination of aquifers with metal ions, as well as marine environments with oil spills and water bodies with organic dyes. Furthermore, synthetic fibers exhibit a superior performance owing to their tunable surface area and superhydrophobic/swelling properties. This review summarizes the most recent advances in natural fiber-based biosorbents and synthetic fiber mats since the efficient removal of toxic compounds depend on adequate incorporation of functional groups on the fiber surface for mutual electrostatic and diffusion of contaminants into the fibrils. The most relevant results in the removal of oil, trace metal ions, and organic dyes are presented and evaluated. The evaluation is done according to the strategies for chemical modification of raw materials by the reuse of plastics or conventional electrospinning techniques to support the hierarchical growth of more complex chemical structures.

“…The adsorption capacity of the nanofiber membrane reached up to 88.2 mg/g at a temperature of 25°C and a pH of 6.5 after adsorption for 30 h. The experimental results showed that the adsorption behavior of composite nanofibers followed the Weber's intraparticle diffusion model, pseudo-secondorder model, and Langmuir isothermal model. A thermodynamic analysis indicated that endothermic, spontaneous, and physisorption processes occurred [30].…”

Dyes have been used in several industries, like paper-making, textiles, plastic, leather tanning, cosmetic and foods industries since Eighteenth century. Effluents containing dyes reduce the penetration of sunlight into natural bodies of water, thus leading to a decrease of both photosynthetic activity and the concentration of dissolved oxygen. The presence of dyes in watercourses is both aesthetically unacceptable and also toxic to aquatic ecosystem and human health. The effluent treatment technologies being used now a days for removal of dyes from wastewater includes coagulation, biological methods, adsorption, advanced oxidation processes, membrane technology, electrochemical methods, nano technology etc. In this review, extensive information is presented with regard to different techniques adopted for dyes removal from the available literature.

“…Cellulose nanoparticles were also used for membrane modification, hence, nanocellulose-enabled membranes were tested in dye removal experiments, exhibiting a dye removal efficiency of 70–80% [ 13 ]. In addition, modified Cellulose acetate nanofibrous membranes were applied efficiently for removing methylene blue (MB) from water [ 14 ]. Furthermore, metal–organic frameworks (MOFs) was tested for anionic and cationic dyes removal by adsorption and a zirconium-metalloporphyrin MOF [ 15 ], or a polyoxometalate (POM) composite [ 2 ], were used to enhance their adsorption capacity in aqueous solution.…”

Dyes are known as one of the most dangerous industrial pollutants which can cause skin diseases, allergy, and provoke cancer and mutation in humans. Therefore, one of the important environmental issues is the effective removal of dyes from industrial wastewater. In the current work, BaFe12O19/CoFe2O4@polyethylene glycol (abbreviated as BFO/CFO@PEG) nanocomposite was synthesized and evaluated regarding its capacity for adsorptive removal of a model dye Acid Blue 92 (denoted as AB92) from aqueous solutions. The characteristics of the prepared nanocomposite was determined by tests such as X-ray diffraction (XRD), scanning electron microscope (SEM), vibration sample magnetization (VSM), and Fourier transform infrared spectroscopy (FTIR). The effects of conditional parameters including pH (2–12), initial concentration of dye (20–100 mg/L), adsorbent dosage (0.02–0.1 g/L) and contact time (0-180 min) on the adsorption of dye were investigated and then optimized. The results indicated that with the increase of the adsorbent dosage from 0.02 to 0.1 g/L, the removal efficiency increased from 74.1% to 78.6%, and the adsorbed amount decreased from 148.25 to 31.44 mg/g. The maximum removal efficiency (77.54%) and adsorption capacity (31.02 mg/g) were observed at pH 2. Therefore, the general optimization conditions revealed that the maximum adsorption efficiency of dye was obtained in condition of initial concentration of 20 mg/L, contact time of 1 h and pH of solution equal 2. The adsorption isotherm and kinetic data were evaluated using a series of models. The pseudo-second order kinetic model and Freundlich isotherm model show the best fitting with experimental data with R2∼0.999.
