采用Tectomer对聚丙烯腈（PAN）纤维进行表面改性，研究了其对二元体系染料的去除能力。采用FTIR、AFM、SEM、BET、BJH等测试手段对纳米纤维进行了表征。FTIR表明通过形成亚胺基团将Tectomer成功接枝到表面。通过AFM和BET分析分别检测到纳米颗粒的平均粗糙度和总表面积的减小。Tectomer接枝改性蒙脱土对直接红80和直接红23的吸附容量分别为1250和1111 mg/g。染料的吸附遵循Langmuir等温线和伪二级动力学。(C)2015年韩国工业与工程化学学会。Elsevier B. V.出版，保留所有权利。
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. All rights reserved.
