The threat of pharmaceutical residues in natural waters is a pressing concern in both developed and underdeveloped countries. Originating mostly from municipal and farms effluents, pharmaceuticals, poorly eliminated by traditional wastewater treatments enter the environment through sewage treatment plants discharges. Their adsorption on ecological adsorptive materials such as lignin may represent an interesting remediation solution. The present study sets out the sorption capacities and properties of a newly developed lignin-based nanofibrous material for typical pharmaceutical residues (fluoxetine, venlafaxine, ibuprofen, and carbamazepine) found in surface waters. This green biomaterial showed, in addition to its high recovery yield, excellent reusability through desorption (more than 90% recovered). As an example, adsorption levels reached 78 mg/g for adsorption of fluoxetine compared to 5-10, 49 and 75-80 for unfunctionalized silica, zeolites and ionexchange resins respectively. The innovative approach reported therein perfectly meets the concept of circular economy sought in modern societies.

“…e advantage of electrospun nanofibres is mimicking of Advances in Materials Science and Engineering three-dimensional structure of natural extracellular matrix, which predetermine them for biomedical and biotechnological application as tissue engineering, wound dressing, and drug release [57,58]. Besides this, it can be synthesised and tailored to suit a wide range of others applications including electronics [59,60], environmental engineering [61,62], agriculture [63,64], and food packaging [65,66].…”

Microscopic techniques are often used in material science, enabling the assessment of the morphology, composition, physical properties, and dynamic behaviour of materials. The review focuses on the topographic and dynamical surface studies of (bio)degradable polymers, in particular aliphatic polyesters, the most promising ones. The (bio)degradation process promotes physical and chemical changes in material properties that can be characterised by microscopic techniques. These changes occurring both under controlled conditions as well as in the processing stage or during use indicate morphological and structural transformations resulting from the deterioration of the material and have a significant impact on the characteristic of materials used in many applications, for example, for use as packaging.

“…The excreta generated by human activities increased the contamination levels to a larger extent. Camera and coworkers characterized the presence of functional groups such as alcohol, ether, and aromatic rings (van der Waals forces, hydrogen bonds, electrostatic interactions, and π–π stacking) on electrospun lignin nanofibers which helped in removing 70% of pharmaceutical contaminant (fluoxetine) from waste water . Tetracycline, another major pharmaceutical pollutant was removed using chitosan blended with PVA nanofibers via chemical crosslinking by glutaraldehyde.…”

The concentrations were optimized to volumetric ratio of 75:25 (chitosan:PVA) using response surface methodology which showed good adsorption capacity (102 mg g −1 ).…”

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.
