摘要：

The surface of polyacrylonitrile (PAN) nanofiber was modified by Tectomer and its dye removal ability from binary systems was studied. The characteristics of nanofibers were investigated by FTIR, AFM, SEM, BET and BJH methods. FTIR showed successful grafting of Tectomer to the surface through the formation of imine group. Decrease in the average roughness and total surface area of nanofiber were detected by AFM and BET analysis, respectively. The adsorption capacity of Tectomer grafted nanofiber for Direct Red 80 and Direct Red 23 was 1250 and 1111 mg/g, respectively. Adsorption of dyes follows the Langmuir isotherm and pseudo-second order kinetics. (C) 2015 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.
