Hydrolysis of oxidized polyacrylonitrile nanofibrous webs and selective adsorption of harmful heavy metal ions

Polyacrylonitrile (PAN) nanofibrous webs were prepared by electrospinning, and then stabilized by a heat treatment. Through these processes, oxidized PAN (oxy-PAN) nanofibers were obtained. After the stabilization, the residual nitrile groups on the surface were hydrolyzed using a high concentration...
