- W1993728147 abstract "We fabricated hybrid nanofibrous mats by electrospinning a polyacrylic acid (PAA)/polyvinyl alcohol (PVA) mixture polymer solution, with multiwalled carbon nanotubes (MWCNTs) incorporated into the nanofibers to enhance their mechanical durability. The mats were further immobilized with zero-valent iron nanoparticles (ZVI NPs) as an active agent for potential environmental applications. Herein, we systematically evaluated the interaction between Cu(II) ions and these MWCNT-reinforced ZVI NP-containing nanofibrous mats in aqueous solutions. Both equilibrium and kinetic behaviors were experimentally assessed, and the influential factors such as pH, contact time, and solution ionic strength were examined. The results indicate that Cu2+ chemisorption occurs via chemical reduction and deposition on the ZVI NP surfaces to form Fe/Cu alloy. The uniform ZVI NPs contained in the hybrid nanofibers offer great specific surface areas that enable very effective, high capacity and strong sorption of Cu(II) ions. The study suggests that the hybrid mats immobilized with ZVI NPs can be a useful material for the removal of Cu(II) ions, and likely many other heavy metal ions, from water, and provides a basis for further development." @default.
