“…Environmental studies related to the use of polysaccharide electrospun fibres were carried out by Huang et al [ 46 ] and Nthunya et al [ 47 ], who exploited chitosan-based fibres to remove metal ions and phenols, respectively. Recently, Mantripragada et al [ 48 ] reported the use of soy protein-coated cellulose-based electrospun membranes for the remediation of emerging contaminants from water.…”

Maltodextrins are products of starch hydrolysis that can be processed into dry fibres through electrospinning and subsequently cured via mild thermal treatment to obtain nonwoven cross-linked polysaccharide-based mats. The sustainability of the process and the bioderived nature make this class of materials suitable candidates to be studied as renewable sorbents for the removal of contaminants from water. In this work, electrospinning of water solutions containing 50% wt. of commercial maltodextrin (Glucidex 2®) and 16.6% wt. of citric acid was carried out at 1.2 mL/h flow and 30 kV applied voltage, followed by thermal curing at 180 °C of the dry fibres produced to obtain cross-linked mats. Well-defined fibres with a mean diameter of 1.64 ± 0.35 µm were successfully obtained and characterised by scanning electron microscopy, thermogravimetric analysis, and attenuated total reflectance Fourier transform infrared spectroscopy. Afterwards, a series of sorption tests were conducted to evaluate the effectiveness of the mats in removing atenolol from water. The results of the batch tests followed by HPLC-UV/Vis showed high sorption rates, with over 90% of the atenolol removed, and a maximum removal capacity of 7 mg/g. Furthermore, continuous fixed-bed sorption tests proved the positive interaction between the polymers and atenolol.

“…Algae contain bioactive components such as polysaccharides, proteins, lipids, vitamins, and minerals [13,14], and the functional groups in algae have exhibited great potential to remove heavy metals, dyes, polyaromatic compounds, and pharmaceutical compounds from wastewater [15,16]. Our recent research revealed that soy protein coating can significantly improve the GenX adsorption efficiency of cellulose-based nanofibers [17]. Considering the protein component in algae and the difficulty of electrospinning standalone algae, the incorporation of algae in PAN nanofibers through electrospinning could inject sustainability to PAN nanofibrous adsorbent/filter materials with much potential to enhance the effectiveness of GenX remediation from water.…”

As a short-chain PFAS (per- and polyfluoroalkyl substance), GenX was produced in recent years to replace traditional long-chain PFASs, such as perfluorooctanoic acid (PFOA). However, GenX turns out to be more toxic than people originally thought, posing health risks as a persistent environmental pollutant. In this research, for the first time, we incorporated chlorella, a single-celled green freshwater microalga that grows worldwide, with polyacrylonitrile (PAN) in equal amounts in electrospun nanofibers and studied the capability of the electrospun PAN/Algae bicomponent nanofibrous membrane (ES(PAN/Algae)) to bind and remove GenX from water. The incorporation of algae demonstrated a synergistic effect and significantly improved the GenX removal efficiency of the nanofibrous membrane. The maximum GenX removal capacity reached 0.9 mmol/g at pH 6, which is significantly higher than that of most of the reported GenX adsorbents as well as activated carbon. The GenX removal mechanism was investigated and discussed by using water contact angle, zeta potential, FTIR, and XPS techniques. This research demonstrated the potential to make highly efficient adsorbent/filter materials from common and economic materials to practically remediate short-chain PFASs from various water bodies.
