Cadmium is a harmful pollutant in soil. Here, an aminated polyacrylonitrile (PAN) nanofiber membrane is obtained by electrospinning and amination modification for effective in situ remediation of bivalent cadmium (Cd(II)) contaminated kaolin. The aminated PAN (APAN) nanofiber membrane has the potential to be used as permeable reactive barrier (PRB) combined with electrokinetics (EK) for the remediation of potentially toxic metal contaminated soil. Morphology and chemical characterizations of the nanofibers are analyzed by scanning electron microscopy and attenuated total reflectance Fourier transform infrared spectroscopy. The maximal adsorption capacities of Cd(II) on APAN nanofiber membrane, as calculated from the Langmuir model, are 51.8 mg g−1. In addition, the obtained APAN nanofiber membrane can also be facilely regenerated through the adsorption/desorption experiments (5 cycles). The APAN‐15 nanofiber membrane is used for the remediation of Cd(II) contaminated kaolin. The pH, water content, conductivity, and Cd(II) concentration of kaolin are detected after EK process. These results show that the APAN‐15 nanofiber membrane works as adsorption medium and can accelerate the migration rate of Cd(II) in kaolin, stabilize the pH, and water content. The APAN nanofiber membrane as PRB material can remove Cd(II) in soil effectively and remediate the soil via the EK/APAN process.

“…The effects of intaking the drinking water whose Cd 2+ concentration exceeds the limit ingestion are inducing kidney disease and bone disease (Zhang et al 2019). The Japanese "itai-itai" disease is the worst event in the Cd 2+ pollution incident, and it is included in the eight major pollution incidents (Huang et al 2020a).…”

Ca 2+ and Mg 2+ usually exist in natural water. When Cd 2+ is removed from water by adsorption, it will be inhibited by these two ions. Titanate nanotubes (TNTs) have an effective adsorption capacity for Cd 2+ due to extraordinary ion-exchange property.However, TNTs also adsorb Ca 2+ and Mg 2+ in water. In this study, carbon-modified TNT (TNT/C or TNT/HC) was synthesized by hydrothermal synthesis. The transmission electron microscope (TEM) images show that TNT/C or TNT/HC still keep nanotube morphology. The experimental results show the order of adsorption amount to Cd 2+ is TNT > TNT/C > TNT/HC when there is no Ca 2+ or Mg 2+ . But when there is Ca 2+ or Mg 2+ in the water, the order of Cd 2+ adsorption capacity becomes TNT/HC > TNT/C > TNT. It indicates that the surface carbon-modification can alleviate the hindrance of Ca 2+ or Mg 2+ to Cd 2+ removal. This is because the carbon on the surface of TNT captured part of Ca 2+ or Mg 2+ , it made more Cd 2+ be successfully absorbed by TNT through ion exchange. This mechanism was confirmed by XPS spectra analysis. The results of this paper can provide ideas for the adsorption and removal of Cd 2+ in water in the presence of Ca 2+ or Mg 2+ .

“…These are a group of storage proteins, with high proline amino acid content, found mainly in the seeds of plant cereal grains, such as wheat (gluten), sorghum (kafirin), corn (zein), and barley (hordein). These proteins can be spun into nanofibres which are completely biodegradable 110,111 . Prolamin‐based protein is currently used in the food industry owing to the high glutamine and proline content.…”

The global coronavirus disease 2019 (COVID‐19) pandemic has rapidly increased the demand for facemasks as a measure to reduce the rapid spread of the pathogen. Throughout the pandemic, some countries such as Italy had a monthly demand of ca. 90 million facemasks. Domestic mask manufacturers are capable of manufacturing 8 million masks each week, although the demand was 40 million per week during March 2020. This dramatic increase has contributed to a spike in the generation of facemask waste. Facemasks are often manufactured with synthetic materials that are non‐biodegradable, and their increased usage and improper disposal are raising environmental concerns. Consequently, there is a strong interest for developing biodegradable facemasks made with for example, renewable nanofibres. A range of natural polymer‐based nanofibres has been studied for their potential to be used in air filter applications. This review article examines potential natural polymer‐based nanofibres along with their filtration and antimicrobial capabilities for developing biodegradable facemask that will promote a cleaner production.
