Electrospun Zeolite/Cellulose Acetate Fibers for Ion Exchange of Pb 2+

The ion exchange capability of electrospun cellulose acetate (CA) fibers containing zeolite A nanoparticles is reported. Solid and porous CA fibers were used to make a zeolite-embedded filter paper, which was then used to ion exchange Na + with Cu 2+ and Pb 2+ . The composite Linde Type A (LTA) zeolite CA fibers exchanged 0.39 mmol/g more Pb 2+ than LTA nanoparticles in the solid CA fibers. These fibers could provide a
