Silk fibroin/cellulose acetate blend Nanofibrous membranes were prepared by electro-spinning and their performances were evaluated as a heavy metal ion adsorbent. The electrospun nanofibrous membranes were comprised of randomly oriented ultra-fine fibers of 100-600nm diameters. As a result of field emis...
