“…31 Therefore, as reported earlier, pH 7 was selected as the optimum medium. 7 The mechanism of adsorption on the surface of the adsorbent beads was investigated using several kinetic models. Pseudo-first-order, pseudo-second-order and intraparticle diffusion equations were used to find the best-fitted model.…”

“…The adsorption performance, regeneration ability and adsorbent separation are other important features of an effective adsorbent. 7 Much research has been carried out on the use of biodegradable polymers with high adsorption capacities. The use of highly abundant low-cost renewable bioresources allows the development of products with a low impact on the environment.…”

Modified regenerated cellulose beads functionalized with activated carbon (AC), as well as magnetic cellulose beads of AC-Fe 3 O 4 and AC-CoFe 2 O 4 , were synthesized. The AC was further used as adsorbent for the removal of cationic methylene blue (MB) dye from aqueous solution. The magnetic cellulose beads possessed a high magnetic response to an external magnetic field and their ease of recovery could be facilitated with the aid of a magnetic field. The synthesized adsorbents were characterized using a Field Emission Scanning Electron Microscope (FESEM), as well as by energy dispersive X-ray (EDX) spectrometry and thermogravimetric analysis (TGA). In comparison with the synthesized magnetic cellulose beads, the maximum adsorption capacity of the adsorbent beads assisted with AC, AC-Fe 3 O 4 and AC-CoFe 2 O 4 was of 54, 53 and 50 mg/g, respectively. The kinetic study of the adsorption of MB dye onto the adsorbents was performed at different parameters (initial dye concentration and temperature). The kinetics of the adsorption fit well with the pseudo-second-order model.

In this study, a novel and low-cost method was developed for synthesizing magnetic porous g-Fe 2 O 3 /C as an adsorbent and catalyst for removal of methylene blue (MB) from aqueous solution. Using FeCl 3 $6H 2 O and bagasse as the precursor, the biomass-based material was synthesized rapidly using a microwave heating process. Fe ions were introduced to achieve both adsorption and catalytic degradation by the

“…Further, Sajab and coworkers loaded graphene oxide–cellulose nanofibril aerogels with Fe(III) ions. The removal is based on Fenton oxidation mechanism, which in the presence of hydrogen peroxide lead to the degradation of methylene blue and achieved a significantly higher efficiency of 30.4% than unloaded fibers . Liu and coworkers enhanced the capacity of hydrogels by (15–23%) deacetylation of chitin nanofibers.…”

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.
