Preparation and performance of silver-incorporated antibacterial amidoximated electrospun nanofiber for uranium extraction from seawater

To avoid the interference of biofouling on the adsorbents towards uranium extraction from seawater, a silver-incorporated antibacterial amidoximated nanofiber adsorbent (PAO@AgNP) was designed and prepared via electrospinning in this study. The uranium adsorption experiments conducted in uranium-spiked seawater showed the material possessed good uranium adsorption capacity (11.89 mg/g), and the antibacterial experiments demonstrated that PAO@AgNP could effectively remove Escherichia coli and Staphylococcus aureus, the released silver could interrupt cellular respiration, lead to lipid peroxidation and eventually apoptosis.
